6.3 Explore: Identifying Quadratic Functions from their Graphs

Determine whether a function is a quadratic function by looking at its graph. If the graph of a function is a parabola, then the function is a quadratic function. If the graph of a function is not a parabola, then the function is not a quadratic function. 
Use a graphing calculator to graph each of the functions. Set the viewing window to show -10 to 10 on both axes. Determine whether each function is a quadratic function.
