Answer 1

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 water level. you may create a sample polynomial to be used in your explanation.

Answer 2

So do you know what the graph of the derivative represents when the graph crosses the x axis?

Answer 3

um no..thats all that it says..

Answer 4

I mean you should know this, its not going to be given in the problem.

Answer 5

But I don't , so can you help ?
