Question

For the functions f(x) = 2x + 2 and g(x) = 7x + 1, which composition produces the greatest output?

Both compositions produce the same output.
Neither composition produces an output.
f(g(x)) produces the greatest output.
g(f(x)) produces the greatest output.

Answer 1

someone help me please!!!!!!!

Answer 2

yes king bruuh plz help me cause i like how you explain

Answer 3

I hope this help for doing 2x+2 but you

Answer 4

but you'll have to fill out the rest of the chart if you want

Answer 5

But I think its g(X)= 7x+1 cause you pick any number for X plug it in and do the math you'll get a higher number than you would if you were to plug in a number the the f(X)= 2x+2

Answer 6

so then its C

Answer 7

actually, I think you may be misunderstanding the problem

Answer 8

The question is not asking to compare f(x) and g(x), it's asking to compare f(g(x)) and g(f(x))

Answer 9

"composition" means to plug one function into the other function

Answer 10

but i think its C

Answer 11

W.e I was taught the way I sorta explained it. But @Papi_Chulo305 you can listen to the others just in case

Answer 12

what is f(g(x))?

Answer 13

I also think it C

Answer 14

Hm, I don't think so

f(g(x)) = 2(7x+1) + 2 = 14x + 2 + 2 = 14x + 4
g(f(x)) = 7(2x+2) + 1 = 14x + 14 + 1 = 14x + 15

g(f(x)) is bigger so I believe the answer is D

Answer 15

THX

Answer 16

but do you understand what I did?

Answer 17

YES

Answer 18

thats what i meant

Answer 19

Oh, I see, sorry then D:
