What things need to be done to graph a quadratic function? Well, first, find the axis of symmetry, then find the vertex of the parabola, then create a table and plug in some x-values to get the resulting y-values. Now write the values as...

Identify the form of a quadratic function that immediately reveals a given feature of that function. Features in question are the y-intercept of the graph, the zeroes ("roots") of the function, and the vertex of the parabola. Students...
