This activity was designed for students to work in pairs and should be used after students in Algebra 1 class have studied key features of quadratic functions (x and y-intercepts, symmetrical aspects of a parabola and minimum and maximum points). Also, some exposure to the formula
h(x) = -1/2gt^2+vt+h and factoring skills are needed. Students should be fluent enough on the graphing calculator to graph a quadratic equation set the window, and determine maximum and zeroes.
F.IF.4 For a function that models a relationship between two quantities, interpret key features of graph and tables in terms of the quantities, and sketch graphs showing key features given a verbal description of the relationship. Key features include: intercepts; intervals where the function is increasing, decreasing, positive, or negative; relative maximum and minimums; symmetries; end behavior; and periodicity.
