We learned to graph functions in standard form and show intercepts, maxima, and minima. We compared the properties of quadratic functions presented in different forms (algebraically, in a table, graphically).
We learned to compare properties of quadratic functions. We found the x-coordinate of the vertex by using the formula –b/2a. Next, we plugged the x-coordinate into the original equation to find the y-value. Then we applied these principles to real-world problems.
