Let f(x) = x + 7 and g(x) = x – 2. What is f(x) • g(x)?
You're told f(x)= x+7. That means that x+7 is the same as f(x). Same goes for g(x). So when they're asking you to multiply f(x) with g(x), what would you replace as f(x) and g(x)?
7 and -2?
Is 7 the same as f(x). What did I say is equal to f(x)?
So what would you replace as f(x)?
x+7? or 7x?
where'd you get 7x from?
Math is all about being realistic. If you did't know where you got 7x, then why would you even bring it out into thin air?
x+7 is correct.
What would you replace g(x) then?
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.
so then using what you just knew about f(x) and g(x): \[f(x)\times g(x)=?\]
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
Wowza, That's awesome! See, if you're actually thinking straight, you can do amazing things. That's absolutely correct!
why thank you :)
