Question

Randy is taking his math SAT. To revive full credit, he must answer this question: What key features are necessary and how are the features used to create a sketch of this polynomial function? What is Randy’s correct answer, so he revolves full credit for the question? Please explain in full sentences.

Answer 1

The key features of the polynomials are the vertex, axis of symmetry, x and y intercepts.

1. The degree will help you to find the end behaviour.

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
