Question

Help me .

Answer 1

lol

Answer 2

if \[f(x)=x ^{2} \] and \[g(x)=x+4\] find:
A) ( fog ) (x)
B) (fog) (2)

Answer 3

@math>philosophy shut up lol

Answer 4

do you know how to evaluate composite functions

Answer 5

no

Answer 6

take the function g(x) and put it into the variable for f(x) so f(x) = (x+4)^2 right

Answer 7

yeah .. lol

Answer 8

so just plug in whatever you want to

Answer 9

Answer 10

No

Answer 11

yes

Answer 12

NO

Answer 13

yes

Answer 14

okay .

Answer 15

good

Answer 16

Shut up

Answer 17

f(x)=x^2


f(g(x))=(g(x))^2


f(g(x))=(x+4)^2


(f o g)(x)=(x+4)^2

Answer 18

optionally, you can expand (x+4)^2 to get x^2 + 8x + 16, but again, it's optional in my view

Answer 19

to find (fog) (2), you plug x = 2 into (f o g)(x)=(x+4)^2 to get

(f o g)(x)=(x+4)^2

(f o g)(2)=(2+4)^2

I'll let you finish

Answer 20

(fog)(2)= (6)^2

Answer 21

keep going

Answer 22

(fog)(2)= 12?

Answer 23

36*

Answer 24

36, yes

Answer 25

so the answer is fog(2)=36?

Answer 26

yep

Answer 27

Thank you(:
