Answer 1

@iGreen. i did one by myself, this is the last one

Well I would just say graph it and see what happens if you mess around with a positive/negative leading coefficient etc or even/odd degrees etc... read into end behaviors of graphs!

But for now

Let me ask what x^3 looks like as a graph:



Looks something like that, see how it starts from the bottom left and goes up to infinity on the right?

well, what would happen if we put a '-' in front of that x^3?

we would instead get:



Something that looks like that...when you put a negative sign in front "the leading coefficient" it would flip the graph...and now it starts at the top left like we want

What did we change? The leading coefficient
