Question

Given f(x)=10x+8 and g(x)=1x+4
then what is f(g(3)) ?

Answer 1

first we need the value of `g(3)`

Answer 2

g(x) = 1x+4


g(3) = 1*3+4 ... replace every x with 3


g(3) = ______ (fill in the blank)

Answer 3

f(x)=10x+8
and g(x)=1x+4

Answer 4

yes you already posted that

Answer 5

id understand

Answer 6

g(x) = 1x+4


g(3) = 1*3+4 ... replace every x with 3


g(3) = ______ (fill in the blank, tell me what you get here)

Answer 7

7

Answer 8

good

Answer 9

so we can replace the `g(3)` with `7` since they are equivalent

Answer 10

`f(g(3)) ` will turn into `f(7)`

Answer 11

to compute f(7), you follow similar steps done to compute g(3)

Answer 12

alright

Answer 13

38

Answer 14

38 is not correct

Answer 15

you might have plugged in x = 3 by mistake

Answer 16

yes

Answer 17

go back up and see why we're plugging in x = 7 instead

Answer 18

is it because g(x) was 7

Answer 19

it's because the output g(3) is equal to 7

Answer 20

alright

Answer 21

anyways, what is the value of f(7) ?

Answer 22

78

Answer 23

correct, that is the final answer

Answer 24

thanks
