For each polynomial function below, make a table that includes integer ‑values from to and sketch each graph.

  1. Continuous, connected, curved graph, decreasing from top left, turning at the following approximate points: low vertices: (negative 1, comma 0), & (1, comma 0), & high vertex, at (0, comma 1), with x intercepts, at negative 1, & 1.

  1. Use the same method as in parts (a) and (b).

  1. Recall that the degree of a polynomial is the highest power of the variable when the polynomial is written in standard form. What is the degree of each polynomial in parts (a) through (c)?

    Rewrite parts (a) and (b) in standard form.
