rse of the function ? A. B. C. D.

Answer 1

x + 3 / 2 = y

Explanation:

to change a function to its inverse we need to do three basic things

1. change f(x) to y

so for the example i gave which is f(x) = 2x - 3; this will now be

y = 2x - 3

2. we need to switch the position of the x's and y's, that means x becomes y and y becomes x

x = 2y - 3

3. finally we make y the subject of the formula

x + 3/ 2 = y, this new expression for y is the inverse of the function and can be written as

f^-1(x) = x + 3/2
