Question

I am really struggling with this. Can anyone help?
Let f(x) = x + 8 and g(x) = x2 − 6x − 7. Find f(g(2)).

Answer 1

Find g(2) first. Can you find it out?

Answer 2

please explain how

Answer 3

plug in x =2 in g(x)

Answer 4

plug means replace x with 2

Answer 5

so 2 +8

Answer 6

and 2*2-6*2

Answer 7

g(2) = 2^2 - 6*2 - 7

Answer 8

4-12-7

Answer 9

yes

Answer 10

-15

Answer 11

yes

Answer 12

theres no option for that

Answer 13

you're not finished

Answer 14

g(2)=15

Answer 15

g(2) = -15

Answer 16

yes i forgot the -

Answer 17

ok, now find f(g(2))

Answer 18

how

Answer 19

what does g(2) equal?

Answer 20

-15

Answer 21

replace g(2) with -15

Answer 22

they would both be -15?

Answer 23

Nope, the question asks for f(g(2)), right?

Answer 24

yeah im confused on how

Answer 25

f(g(2)) = f(-15) because g(2)= -15, right?

Answer 26

yes

Answer 27

Now you just need to find f(-15)

Answer 28

f(x) = x + 8

Answer 29

replace x with -15
