And given the function g(x), which is:
You need to substiute the function into the function in order to find 
.

You can observe that this matches with the second option.
Y=X-10
Step-by-step explanation:
Step 1:
Let X be the input and Y be the output variable
Given: The output is 10 less than the input
Step 2:
Y=X-10 be the require function
Eg:
for X=1, Y = -9
X=2, Y=-8, etc
The answer to that question is x^2 +4x
I'm pretty sure the answer is 33, hope this helps!
