2-43.

The vertex of a parabola, point **locator point** for a parabola. Other families of functions that you will be investigating in this course will also have locator points. These points have different names, but the same purpose for each different type of graph. These points help you place the graph on the axes.

Sketch graphs for both of the following functions. On each graph, label the locator point. Homework Help ✎

The locator point is

and the graph has a stretch factor of . The locator point is

and the parabola is flipped over.
