Question

Let f(x) = x + 8 and g(x) = x2 - 6x - 7. Find f(g(2)).

-7

-3

10

33

Answer 1

First find f(g(x))

Answer 2

Can you do that right now please?

Answer 3

f(x)=x+8
x^2-6x-7+8
-13x+8
=x^2-5x

Answer 4

\[f(g(x)) = (x^2-6x-7)+8\]

Answer 5

\[f(g(2)) = ((2)^2-6(2)-7)+8\]

Answer 6

(4-12-7)+8=-7

Answer 7

yes
