Question

CAN SOMEONE PLEASE HELP ME WITH FUNCTIONS?! WILL GIVE MEDALS

Answer 1

I'll give you more medals if you break the suspense and ask the specific question :)

Answer 2

Okay, i have a few questions I need help with. Here is the first one. I seriously just don't get it.
Given that f(x) = 4x - 3 and g(x) = solve for g(f(2)).

1
3
9
15

Answer 3

Will you walk me through the steps on how to do this? I don't get it.

Answer 4

I believe you just have to replace the x in the function with 2 in order to find g(f(2))

Answer 5

Okay, I'll try that.
I'll let you know what I end up getting.

Answer 6

I replaced x with 2, and I got 6...which is not an option...

Answer 7

Are you sure those are the answer choices?

Answer 8

Positive

Answer 9

@ganeshie8 please, help?

Answer 10

I have been searching for the function g(x) but couldn't find it out, could you please confirm if its missing at your end also ?

Answer 11

`f(x) = 4x - 3 `

where is g(x) ?

Answer 12

g(x) = 2x-1
-------
3

Answer 13

thanks!
so you have got f(2) = 6 earlier right?

Answer 14

but the question is not just about f(2),
they want you find g(f(2))

Answer 15

I don't get how to do this at all. And no, I got 5 for the first equation, and 1 for the second equation. And I added them together.

Answer 16

i have no idea what I'm doing.

Answer 17

Oh ok

Answer 18

so you got f(2) = 5

Answer 19

g(f(2)) = g(5)

evaluate the function g at 5

Answer 20

g(x) = 2x-1
-------
3


g(5) = ?

Answer 21

g(x)=3?

Answer 22

Where did you get the 5 from?

Answer 23

@ganeshie8

Answer 24

5 is from the first function you solved.

Answer 25

g(5) = 3 is correct !

Overall :
g(f(2)) = g(5) = 3

Answer 26

Okay, thank you! Can I ask a few more? I think I only need help with like 2 or 3 more.
