A student claims that 1,2,3 and 4 are the zeros of a cubic polynomial function. Explain why the student is mistaken. Give an example to support your answer.
A cubic function only has 3 solutions at which x = 0, never 4. For example the function y = [tex]y = x^{3} + 3x^{2} + 2x[/tex] gives the solutions: x = 0, x = -1 and x = -2
