Question 969595: Sketch a graph and find one possible equation for a polynomial function f(x) with x intercepts at -2 and 1, a y intercept at 5 and where f(x) = -infinity and f(x)=infinity.
I came up with f(x)= -(5/4)x^cubed - (15/4)x^2 +5. Not sure if this is correct, but it does make a graph that looks correct. Is this a possible equation for this scenerio?
