The change in water level of a lake is modeled by a polynomial function, W(x). Describe how to find the x-intercepts of W(x) and how to construct a rough graph of W(x) so that the Parks Department can predict when there will be no change in the water level. You may create a sample polynomial of degree 3 or higher to use in your explanations.

@mastermindkakashi  any ideas?

anonymous · Answer

Okay lets see here

anonymous · Answer

So basically its just asking for you to find the x-intercepts of the function W(x), and how to graph it (a rough sketch)

anonymous · Answer

Do you know how to find and do these?

anonymous · Answer

no:(

anonymous · Answer

Could u explain it so i can get it?

anonymous · Answer

Ok.To find the x- intercepts, or zeroes, of w(x), we use the rational root theorem to find all possible roots, where p is the constant term and q is the leading coefficient.

anonymous · Answer

Just search up the rational root theorem and take a look at it and come back, it needs examples to help you get it

anonymous · Answer

ok. I know how to do that

anonymous · Answer

Or, as I did, when i took flvs algebra 2 i looked it up in the chapter summaries

anonymous · Answer

?? Ok:)
