Per:
LT 3E I can graph and interpret the key features of a polynomial function and its graph, including intercepts, domain, range, and intervals where the function: is
increasing/decreasing, positive/negative, has a relative maximum/minimum, has symmetry
LT 3F I can determine the degree of a polynomial from a table, and write a polynomial function that describes the relationship between two quantities using
zeros and one additional point.
