I think 77 is my right anwer
You are tackling a trigonometry question here. I recommend remembering the functions and drawing the triangle out.
Answer:
Axis of Symmetry = -4
Vertex = (-4,7)
Step-by-step explanation:
37.5 and 3750% because 100 divided by 8 is 12.5 . 12.5 x 3 equal 37.5 which is your decimal and you move the decimal two places to the right to get 3750%
You just need to plug 12 in for x in the equation.
f(12)=4(12)+5
f(12)=53
