−21
−3
3
21

Answer 1

Let f(x) = x − 2 and g(x) = x2 − 7x − 9. Find f(g(−1)).

g(-1)=-1^2-7(-1)-9
g(-1)=1 + 8 - 9
g(-1)= 0
f(g(-1)) = 0 - 2
= -2
Are those answer choices correct

Answer 2

Those are the only answer choices they gave me :(

Answer 3

Aw, maybe I did something wrong then O_o

Answer 4

Wait
I did

Answer 5

My bad

Answer 6

g(-1)=-1^2-7(-1)-9
g(-1)=1 + 7 - 9
g(-1)= -1
f(g(-1)) = -1 - 2
= -3

Answer 7

Lol I chose -3 because it was the closest to your answer and I got a 100 on the test. So thanks for your help on both questions :)

Answer 8

There it is xD Sorry
