Hero · Answer

So just to clarify:
$f(x) = \dfrac{x - 8}{7}$ and $g(x) = 7x + 8$

Is that correct as written?

simplymariex · Answer

Yes, that's it. :-)

Hero · Answer

Okay, great. So we have to perform $g(f(x))$.

Hero · Answer

Question, if someone told you to evaluate something like $g(3)$ would you be able to do that?

Hero · Answer

@simplymariex, thanks for abandoning me. I was going to show you how to do it. I was just trying to see where you were at in terms of your knowledge of this concept. If you are unable to evaluate something like $g(3)$ I would have shown you to help you understand better how to evaluate functions.

@Hero There's no need to be so passive aggressive with me. I lost internet due to heavy rain and winds.

simplymariex · Answer

I managed to figure it out on my own whilst the internet was out but thank you anyways. I'll still award you the medal, even though you feel as if I "abandoned" you.
