Find (f o g)(-6) when f(x)=4x+4 and g(x)=6x^2-3x-6.

I originally came up with 918, but the answer is 916. Obviously I was close, but could someone tell how to get 916. I am studying for a test and am re-working my homework problems. Thanks.

  2. g(-6) = 6*36 - 3*(-6) -6
    = 228
    f(228) = 4(228)+4
    =912 +4 = 916
