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.

    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)

    Do you know how to find and do these?

    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.

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