Question

Can someone please help me. I need to see how to work this. I will give a medal.

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

-7
-3
10
33

Answer 1

f(x)=x+8
f(2)=2+8

Answer 2

i think you need g(2) first right?

Answer 3

g(x) = x2 - 6x - 7
g(2)=(2)^2-6(2)-7

Answer 4

first find g(2) then take f(result)

Answer 5

g(2)=(2)^2-6(2)-7=4-12-7=-8-7=-15

Answer 6

f(g(2))=f(-15)

Answer 7

f(x)=x+8
f(-15)=-15+8

Answer 8

g(2) = (2)^2-6(2)-7 = -15
f(15) = -15 +8 is your answer

Answer 9

ok thank you both for explaining it, I appreciate it.
have a great day.

Answer 10

how much is -15+8 that is your final answer @mlb004
