Question

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

h(x)=1/3x+3

h(x)=1/3x-3

h(x)=x-3

h(x)=x+3

Answer 1

• h(x) = x - 3

Explanation:

Given function

• f(x) = x +3

Inverse of the function is h(x)

To find h(x) replace f(x) with x and x with h(x) in the given function:

• f(x) = x + 3 ⇒
• x = h(x) + 3, and solve for h(x)
• h(x) = x - 3, this is the inverse of f(x)
