Question

let f(x) = n^2 + 2n + 4 and g(x) = -3n +2 Fine (g of f)(1)

Answer 1

Find the f(1) and put that result into the function g.

Answer 2

What is the f(1)?

Answer 3

Thats the whole problem. I'm not good with this sort of problem.

Answer 4

Are you sure that the problem is not f(n)?

Answer 5

g(f(1))?

Answer 6

Ok. Brinethery wants to help you now. Good bye.

Answer 7

Lol huh? I was just making sure what it was.

Answer 8

It says find (g o f)(1)

Answer 9

Merts, you mad at me?

Answer 10

@Mertsj do you have any idea of what to next? I'm not sure what they mean by (g of f)1?

Answer 11

Here's the problem http://i1204.photobucket.com/albums/bb402/Libby_Williams/mod2top5quizq16.jpg

Answer 12

Crap, typo on my work. I mean -3(n^2 + 2n + 4) +2

Answer 13

It seems you don't understand yet what a compound function is.

Answer 14

Ooooh okay.

Answer 15

(n^2 + 2n + 4)(-3n +2)

Answer 16

And then plug 1 in?

Answer 17

There is a problem because f(x) means the function whose variable is x and then we are presented with a function whose variable is n.

Answer 18

So what do I do with 8 and -22?

Answer 19

If we assume that is just a typo and it means f(n), then to find the g(f(1)) means replace n in the function f with 1. Take that result and put it into the function g.
