You would use it by adding 5 for every time you added 8 or just multiply 13 by the number of times you added 8. Either way works.

f(2x−x2)=−3x2+6x−1

step-by-step explanation:

set up the composite function and evaluate.

f(2x−x2)=−3x2+6x−1

the answer is simply just 6n add the two together as they have an n
