Randy is taking his math SAT. To receive full credit, he must answer this question:What key features are necessary-and how are the features used-to create the sketch of a polynomial function?What is Randy's correct answer, so he receives full credit for the question? Explain in complete sentences.

The key features of polynomials are the vertex, axis of symmetry, x and y intercepts. 1.    The degree will help you find the end behavior.2.     The vertex shows you where it changes concavity.3.     X and y intercepts give you a couple of points of reference.4.     Axis of symmetry is only applicable to even degree polynomials. I am hoping that these answers have satisfied your expectations, and if you would like, feel free to ask another question.
