Graph the function y=2x on the domain 0 ≤ x ≤ 3. a Explain why a person who sees only the graph you created not the equation might think that the graph represents a polynomial function. b Explain why this function is not a polynomial function.

A clearly indicated correct answer will receive full marks, regardless of work shown. An in- correct answer could receive part marks if relevant work is shown.
