Comparing a Function and Its Inverse

Question 1

Complete the sentences to compare the functions. The y-intercept of f(x) has the same value as the . The function f–1(x) has a range including all values greater than or equal to 0; therefore, the does also.

Revolt · Accepted Answer

x-intercept of f inverse; The y-intercept of f(x) has the same value as the .: x-intercept of f inverse; The function f–1(x) has a range including all values greater than or equal to 0; therefore, the does also.: domain of f

Question 2

Question 3

The function f(x) = ln(x) has a domain of all real numbers greater than zero and a range of all real numbers. The inverse of this function is f–1(x) = ex. Which conclusion can be drawn by comparing the two functions?

Revolt · Accepted Answer

The domain of f–1(x) is all real numbers and the range is all real numbers greater than 0.

Question 4
