D. 12

Answer 1

13, c

Answer 2

wat

Answer 3

heh i can say D..doesnt make me any more wrong :)

Answer 4

wait i need to fix something

Answer 5

there

Answer 6

first solve for g(-1). i assume you know how to?

Answer 7

could you wlk me through it

Answer 8

to find g(-1) simply replace the x of g(x) with -1

g(x) = x + 3
g(-1) = -1 + 3

Answer 9

so what's g(-1)

Answer 10

2

Answer 11

right. now since g(-1) = 2

f(g(-1) ) = f(2) agree?

Answer 12

agree

Answer 13

so now solve for f(2)

Answer 14

thinking

Answer 15

the answer is 13 after all

Answer 16

lol the person got the answer so quick

Answer 17

lucky guess lol
