We are going to work with function machines differently.
If I say find f(x+2) it means to calculate the output for the input that is 2 greater than x.
We'll use the input 8.
EXAMPLE:
So we have the function: f(x+2)=2x+7
The input is two greater than x so f(8+2) is f(10). f(10)=2(10)+7
Answer: f(10)=27
Find f(x)+12 when the input is 8.
