Answer 1

Find g(4) first

Answer 2

Then plug that into f

Answer 3

\[g(8)=\frac{8+8}{4}\]
what does this =?

Answer 4

Hold on 32 I think

Answer 5

8+8=16
What is 16/4=?

Answer 6

I absolutely suck at these problems.

Answer 7

16/4 =4

Answer 8

Now plug 4 into f(x)

Answer 9

oops i thought we were finding (f o g)(4)

Answer 10

above we are finding (g o f)(4)
you can use this as example to do your problem

Answer 11

Oh noes D:

Answer 12

\[f(g(4))=f(4)=4^2+6\]

Answer 13

=15/11

Answer 14

I'm sorry lol
it is really hard for me to flip back and forth
i got the function for g wrong

Answer 15

Oh. Now I see. It makes sense when you do it with someone but then when you do it alone you're mind screwed. ;/

Answer 16

omg, this is like the second time I have witnessed myininaya make a mistake

Answer 17

\[f(x)=x^2+6 , g(x)=\frac{x+8}{4}\]

Answer 18

Are those the two functions?

Answer 19

I thought g(x) = (x+8)/x

Answer 20

lol I don't know I don't really want to flip back anymore

Answer 21

\[(g o f)(4)=g(f(4))=g(4^2+6)=g(16+6)=g(32)=\frac{32+8}{32}\]
using hero's function for g

Answer 22

actually, f(x) = x^2 + 6

Answer 23

@myininaya , I think it's time to "flip back"

Answer 24

Let me help, so you guy don't have to "dispute" :P

Answer 25

I think it would be easier lib libs if you put the functions here next time. I'm bad this memory thing.

Answer 26

It's 15/11 Right?

Answer 27

I wasn't planning on disputing with anyone.

Answer 28

Yes ma'am~

Answer 29

f(4) = 4^2 + 6 = 22
-> gof (4) = (22 + 8 ) / 22 = 30/ 22 = 15/11

Answer 30

I get 15/11 too

Answer 31

yes because 16+6 equals 22 not 32 lol

Answer 32

that was a type-o

Answer 33

@myininaya You're too professional :)
@Hero you're way formulated :P

Answer 34

@Chlorophyll, what does that make you? I guess you're too Chlorophyll'd

lol
