Question

What is the inverse of the function f(x) = 4x + 8?

Answer 1

Answer: FIRST OPTION.

Step-by-step explanation:

Given the following function:

$f(x)= 4x + 8$

Follow this steps in order to find its inverse:

1. Rewrite the function with $y=f(x)$:

$y= 4x + 8$

2. Solve for "x":

$y-8= 4x\\\\x=\frac{y-8}{4}\\\\x=\frac{y}{4}-2$

3. Now you must exchange the variables:

$y=\frac{x}{4}-2$

4. And finally, rewrite the function with $h(x)=y$:

$h(x)=\frac{x}{4}-2$

Therefore, the inverse function is $h(x)=\frac{x}{4}-2$

Answer 2

Answer:

h(x) = one-quarterx – 2 A
