Question

What is the inverse of the function f(x) = x + 2? h(x) = 18x – 2 h(x) = 9x – 18 h(x) = 9x + 18 h(x) = 18x + 2

Answer 1

Answer:

B (h(x) = 9x - 18)

Step-by-step explanation:

Answer 2

A function g is the inverse of a function f if whenever y=f(x) then x=g(y). The inverse is usually shown by putting a little "-1" after the function name, like this: f-1(y)

In our case the function is f(x)=x+2. 

The inverse function of f(x) is h(x)=x-2

Multiplying this function with 9 gives: h(x)=9x-18
