Question number one

Esmeralda and Heinz are working to graph a polynomial function, f(x). Esmeralda says that the third-degree polynomial has four intercepts. Heinz argues that the function only crosses the x-axis three times. Is there a way for them both to be correct? Explain your answer.  They are both correct because a third-degree polynomial has 3 roots so it can dross the x axis 3 times at most. Since there are 4 intercepts it can have both x and y.
