@jdoe0001 if you could help again, let me know if  I'm annoying you lol. I know what the graphs look like, but i don't know how to describe them

hmmm I guess I'd say.... that g(x) looks like a vertically-stretched horizontally-flipped version of f(x)

Wait.. the first function is a completely separate question than the second question. They are not together in any way

jdoe0001 · Answer

well... ok... then both are of 3rd degree, so that means they'd have 3 roots or 3 solutions or 3 x-intercepts, that is they will have to touch the x-axis 3 times

I think when it says describe though it means like f(x)--> infinity as f(x)--> -infinity or something

jdoe0001 · Answer

hmm domain and range.... so as x goes to $\pm\infty$   y goes also to $\pm\infty$ and

yes  I think that how to describe the end behavior
