Question

(g x f)(x) when f(x) = x+5 and g(x) = 7x

Answer 1

You posted this already? (x+5)(7x) = 7x^2+35x

Answer 2

it's different because this is g x f not f x g

Answer 3

Multiplication does not care about the order.

Answer 4

but online it said it was something like 7(x+5)^2 but then I don't know how to solve from there

Answer 5

OHHHHH. I'm so sorry, I was not understanding the notation you were using. It means g(f(x)) right? so it should be 7(x+5), idk where the squared came from in your last statement.

Answer 6

is the other answer for fxg(x) still right?

Answer 7

No. It would be 7x+5.

Answer 8

and do I distribute the 7 in 7(x+5) or just leave it?

Answer 9

I would distribute the 7 to get 7x+35.
