Question

MULTIPLE CHOICE For which function does the inverse function exist?

A) f(x)=2 –1
C) f(x)=√ + 4
B) f(x)=3 –2x
D) f(x)=–1

Answer 1

f(x) = 3 -2x

Explanation:

first 2 are I don't even know.

last is -1. constant

f(x) = 3-2x can be shown as, y = 3-2x

inverse is x = 3-2y

2y = 3-x

y = (3-x)/2
