Use Descartes’ rule of signs to determine the possible number of positive and negative real zeros for the following function. Then, use a graph to determine the actual numbers of positive and negative real zeros.
P(x)=x3-3x2-33x+35
A) What is the possible number of both positive and negative real zeros of this function?
B) Use the graph of f(x) to determine the actual numbers of positive and negative real zeros.
