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, ∞)

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
