Question

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

h(x) = x + 3
h(x) = x – 3
h(x) = x – 3
h(x) = x + 3

Answer 1

h(x) = x - 3 when using function notation

Explanation:

or C

Answer 2

An inverse of a function can be found by flipping the x and y axis around in the function

So instead of y = x + 3, it would be x = y + 3.

Now you need to solve for y and as a result you should get y = x - 3 [or h(x) = x - 3 when using function notation]
