Question

Will give medal and be a fan. Given f(x)=x^2+3 and g(x)=x+5/x. find (gof)(4). !

Answer 1

okay,so do you want it graphed?

Answer 2

Yeah , the answer i got is 14/19 but i think im wrong

Answer 3

okay, I'm doing this stuff so I think I can figure it out:)

Answer 11

Yeappp

Answer 12

._. so am i right or no

Answer 13

ya there?

Answer 14

@phi

Answer 15

(gof)(4) is short for first find f(4)
can you find f(4) ?

Answer 16

f(x)=x^2+3
f(4) is short for, "replace x with 4, and simplify"

Answer 17

oh okay..i kinda get it...

Answer 18

what do you get for f(4) ?

Answer 19

Sorry im writing it down. is it 15? <

Answer 20

@phi

Answer 21

f(x)=x^2+3

are you saying when x is replace with 4, like this
f(4)= 4^2 +3 you get 15 ? is your calculator broken?

Answer 22

(gof)(4) is short for first find f(4)
can you find f(4) ?
if you can, make that number x in g(x)
g(x)=x+5/x

to find (g o f)(4)

Answer 23

no but ive been doing this work for like 2 1/2 hours.. this is the last one

Answer 24

what do you get for f(4) ?

Answer 25

what do you get for f(4) ?
f(4)= 4^2 +3

what is 4*4 ?
and then add 3.
what do you get ?
