We practiced plotting quadratic functions in standard form with f(x) = ax2 where a>1 or 0<a<1. We learned to identify key features of the graphs of quadratic functions written in vertex form. We learned to graph functions in standard form and show intercepts, maxima, and minima. Then we learned to determine how the values of a, b, and c affect the graph of f(x) = ax2 + bx + c. Next, we compared the properties of quadratic functions presented in different forms (algebraically, in a table, and graphically).
