Question

What is the inverse of the function f(x) = x +3?

Answer 1

Then
x=-3 (to make zero)

Answer 2

Answer:

C. $h(x)=x-3$

Step-by-step explanation:

We have been given a function $f(x)=x+3$. We are asked to find the inverse of the given function.

First of all, we will replace $f(x)$ by y as:

$y=x+3$

Now, we will interchange x and y variables as:

$x=y+3$

Solve for y:

$x-3=y+3-3$

$x-3=y$

Switch sides:

$y=x-3$

Therefore, the inverse function for the given function would be $h(x)=x-3$.
