4-56.

The vertex of a parabola (point (

*h*,*k*)) locates its position on the axes. The vertex serves as a**Locator Point**for a parabola. The other shapes you will be**investigating**in this course also have locator points. These points have different names but the same purpose for each different type of graph.Sketch graphs for each of the following equations. On each sketch, label the locator point. 4-56 HW eTool (Desmos). Homework Help ✎

*y*= 3*x*^{2}+ 5*f*(*x*) = −(*x*− 3)^{2}− 7
