Question

Let f(x) = 9x - 2 and g(x) = -x + 3. Find f(g(x))
I don't know the answer to this problem

Answer 1

f(g(x))=f(-x+3)=9*(-x+3)+3
do you know the rest? :)

Answer 2

that's all it says

Answer 3

no, what i meant to say is that only thing left is to multiply and sum after that :) do you know how to do that by yourself?

Answer 4

so will the answer be -9x+27+3=-9x+30??

Answer 5

yes :) well done

Answer 6

thank you

Answer 7

you're wellcome

Answer 8

Let f(x) = -4x + 7 and g(x) = 10x - 6. Find f(g(x)).

so does that mean -40x + 24 would be the answer for this problem

Answer 9

Woops, I think you got your functions a little mixed up Stephan.
f = 9x-2

So when you plug g into f,
= 9g-2
= 9(-x+3)-2

Should be -2 on the far right, not +3.
Small typo probably :)

Answer 10

oh yes, i mixed it up, sorry :)
