Question

What is the inverse of the function f(x) = x +3?
A. h(x) =1/3 x + 3
B. h(x) = 1/3x – 3
C. h(x) = x – 3
D. h(x) = x + 3

Answer 1

f(x) = x + 3
y = x + 3
x = y - 3

Inverse is h(x) = x - 3

Answer 2

Answer:

Option C is correct that is h(x)=x-3

Step-by-step explanation:

We have been given a function:

$f(x)=x=3$

$\text{let y}=f(x)$

$y=x+3$

$x=y-3$

Hence,$f^{-1}y=y-3$

Therefore, $f^{-1}x=x-3$

Hence, Option C is correct that is h(x)=x-3
