Answer:
22 Nah I'm kidding, it's 4
Step-by-step explanation:
This was fun
Answer:
D
Step-by-step explanation:
2x-5=9
add 5 to both sides
2x=14
divide by 2 on both sides
x=7
Option D:
is the inverse of the function f(x) = 4x
Explanation:
Given that the function is 
We need to determine the inverse of the function.
<u>Inverse of the function h(x):</u>
The inverse of the function can be determined by interchanging the variables x and y and then solving the function for y.
Thus, the function is written as,

Interchanging the variables x and y, we have;

Dividing both sides by 4, we get;

Thus, the inverse of the function is 
Hence, Option D is the correct answer.
