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

2. Azteck Group Title

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)?

3. itsjustme_lol Group Title

7 and -2?

4. Azteck Group Title

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

5. itsjustme_lol Group Title

x+7

6. Azteck Group Title

So what would you replace as f(x)?

7. itsjustme_lol Group Title

x+7? or 7x?

8. Azteck Group Title

where'd you get 7x from?

9. Azteck Group Title

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?

10. Azteck Group Title

didn't*

11. Azteck Group Title

x+7 is correct.

12. Azteck Group Title

What would you replace g(x) then?

13. itsjustme_lol Group Title

x-2

14. itsjustme_lol Group Title

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

15. Azteck Group Title

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

16. Azteck Group Title

horrible at*

17. Azteck Group Title

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

18. itsjustme_lol Group Title

-14?

19. Azteck Group Title

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

20. Azteck Group Title

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

21. itsjustme_lol Group Title

well because idk why i didnt..

22. itsjustme_lol Group Title

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

23. Azteck Group Title

Wowza, That's awesome! See, if you're actually thinking straight, you can do amazing things. That's absolutely correct!

24. itsjustme_lol Group Title

why thank you :)
