A.7- The student will investigate and analyze function (linear and quadratic) families and their characteristics both algebraically and graphically, including
a)   determining whether a relation is a function;
e)   finding the values of a function for elements in its domain; and
f)   making connections between and among multiple representations of functions including concrete, verbal, numeric, graphic, and algebraic
