Which of the following is not a vertex of the figure formed by: y> 5/4x-7/2 and y> -3/2x+2 and y< 1/3x+2

How would you describe the difference between the graphs of f(x) = 2x2 and g(x) = -2x2?

The change in water level of a lake is modeled by a polynomial function, w(x). described 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 chage in the water level. you may create a sample polynomial of degree 3 or higher to use in your explanations.
