Let f(x) = x + 7 and g(x) = x – 2. What is f(x) • g(x)?

7 and -2?

Is 7 the same as f(x). What did I say is equal to f(x)?

x+7

So what would you replace as f(x)?

x+7? or 7x?

where'd you get 7x from?

didn't*

x+7 is correct.

What would you replace g(x) then?

x-2

and sorry..im really horrible at math so i honestly didnt know...goodness lol

Okay that's correct though even if you're horriblea t math. You got it.

horrible at*

so then using what you just knew about f(x) and g(x):
\[f(x)\times g(x)=?\]

-14?

You didn't say anything about -14 beforehand, why now?

I'm just asking you to repeat what you said last time about what f(x) and g(x) is.

well because idk why i didnt..

ok, that make sense i think.
ok so if i got this right my answer would be x^2 + 5x – 14

why thank you :)
