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

h(x) = one-quarterx – 2

h(x) = one-quarterx + 2

h(x) = one-halfx – 2

h(x) = one-halfx + 2

Answer: FIRST OPTION.

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=(y-8)/(4)\\\\x=(y)/(4)-2

3. Now you must exchange the variables:


y=(x)/(4)-2

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


h(x)=(x)/(4)-2

Therefore, the inverse function is
h(x)=(x)/(4)-2
