Answer:
Answer:
f(x) = 5 + 2x
y+4x^2-1 is the same as y=-4x^2+1, then replace y with f(x); f(x)=-4x^2+1. After you do that, replace x with 2; f(2)=-4(2)^2+1. 2^2=4, 4 times -4=-16, -16+1=-15. So f(2)=-15.
*ahem* the actual Awnser is 79.25 because 63.4 divided by 72 is 0.8805 and if you multiply that by 90 you get 79.25
