114 Range of a function For a function f X → Y the range of f is the set of yvalues such that y = f(x) for some x in X This corresponds to the set of yvalues when we describe a function as a set of ordered pairs (x,y) The function y = √ x has range;Question 5292 f(x) = (1/3)^x what would the domain and range of this function be?Domain of a function is the set of all those values of x for which f(x) is a finite real number(Provided we are given a real valued function) Notice that the polynomial 2x1 has a zero at x=1/2 Now if we input this value of x into the function

Answer by oberobic(2304) (Show Source)Solution We have, f(x) = 1 1 − x2 Clearly, f(x) is defined for all x ∈ R except for which x2 − 1 = 0 ie, x = ± 1 Hence, Domain of f = R − { − 1, 1} Let f(x) = y Then, 1 1 − x2 = y ⇒ 1 − x2 = 1 y ⇒ x2 = 1 − 1 y = y − 1 yTherefore, the domain is (∞, 1) U (1, ∞)
Video Transcript were given a function and we're asked to find the domain and range of dysfunction Function is F of X equals one plus X square Notice that the function F is a polynomial function that's a quadratic function and therefore the domain of F is all real numbers Likewise, you know that X squared is always greater than we pull up Find the Domain and Range f(x) = log of x12 f (x) = log (x − 1) 2 f(x)=log(x1)2 Set the argument in log (x − 1) log(x1) greater than 0 0 to find where the expression is defined x − 1 > 0 x1>0 Add 1 1 to both sides of the inequality x > 1 x>1 The domain is all values of x x that make the expression defined Interval Notation (1, ∞) (1,∞) SetBuilder Notation {x x > 1} {xx>1} For example, the function \(f(x)=\dfrac{1}{\sqrt{x}}\) has the set of all positive real numbers as its domain but the set of all negative real numbers as its range As a more extreme example, a function's inputs and outputs can be completely different categories (for example, names of weekdays as inputs and numbers as outputs, as on an
The "" means "such that," the symbol ∈ means "element of," and "ℝ" means "all real numbers" Putting it all together, this statement can be read as "the domain is the set of all x such that x is an element of all real numbers" The range of f (x) = x2 in set notation is R {y y ≥ 0} R indicates rangeDomain and range graph The graph of f(x)=x2 f ( x) = x 2 (red) has the same domain (input values) as the graph of f(x)=− 1 12x3 f ( x) = − 1 12 x 3 (blue) since all real numbers can be input values However, the range of the red graph is restricted to only f(x)≥0 f ( x) ≥ 0, or y y values above or equal to 0 0Function Domain Range ;

For example, a function f (x) f ( x) that is defined for real values x x in R R has domain R R, and is sometimes said to be "a function over the reals" The set of values to which D D is sent by the function is called the range Informally, if a function is defined on some set, then we call that set the domainRational functions f(x) = 1/x have a domain of x ≠ 0 and a range of x ≠ 0 If you have a more complicated form, like f(x) = 1 / (x – 5), you can find the domain and range with the inverse function or a graph See Rational functions Sine functions and cosine functions have a domain of all real numbers and a range of 1 ≤ y ≤ 1Range {yly> 2} domain {x x g According to the United States Postal Service, First Class Mail International (letters) takes 6 to days to deliver to their destination In order to test this, Greg, in Chicago, sent one
All these are real values Here value of domain (x) can be any real number Hence, Domain = R (All real numbers) We note that that Range f (x) is 0 or negative numbers, Hence, Range = (−∞, 0 Ex 23, 2 Find the domain and range of the following real function (ii) f (x) = √ ( (9 −x^2)) It is given that the function is a real function Hence, both its domain and range should be real numbers x can be a number from –3 to 3 f (x) is between 0 & 3 Hence, Domain = Possible values of xWhat is the domain and range?Range {yly>0} domain {x\x> 1/6);
The given real function is f (x) = x − 1 It can be seen that x − 1 is defined for (x − 1) ≥ 0 ie, f (x) = (x − 1) is defined for x ≥ 1 Therefore the domain of f is the set of all real numbers greater than or equal to 1 ie, the domain of f = 1, ∞)1 For f (x) to exist x − x > 0 ⇒ x > x ⇒x is a negative real number Therefore the domain of the function is the set of negative real numbers and range is the set of positive real numbers 501We can see the function a define for all values of x Domain of f(x) = R, where R is the set of all real number When you put any value of x from domain you'll get either '0′ or any positive value for f(x) So, Range of f(x) = 0, ∞) Graphical Method Simply draw the graph and you can see domain & range in graph itself

Call this f1 (x) f1 (x) = sqrt x/(1x) On this last function, the implied domain of the inverse is 0,1) That means that the range of the original function must have been 0,1), alsoDomain and Range The domain of a function f ( x ) is the set of all values for which the function is defined, and the range of the function is the set of all values that f takes (In grammar school, you probably called the domain the replacement set and the range the solution set They may also have been called the input and output of the function)A horizontal line test will give several points of intersection But if we limit the domain to \( \dfrac{\pi}{2} , \dfrac{\pi}{2} \), blue graph below, we obtain a one to one function that has an inverse which
Given that f(x) = 1/√(x 5) Here, it is clear that (x) is real when x – 5 > 0 ⇒ x > 5 Hence, the domain = (5, ∞) Now to find the range put For x ∈ (5, ∞), y ∈ R Hence, the range of fWhat is the domain and range of f (x) = 1/x?For the reciprocal squared function latexf\left(x\right)=\frac{1}{{x}^{2}}/latex, we cannot divide by latex0/latex, so we must exclude latex0/latex from the domain There is also no latexx/latex that can give an output of 0, so 0 is excluded from the range as well Note that the output of this function is always positive due to the square in the denominator, so the range
