    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)?

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

    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?

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

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