4-91.

Use the point (

*h*,*k*) to help you write a possible equation for each graph shown below. Homework Help ✎

Remember that *y* = (*x* − *h*)^{2} + *k*.

Notice that the vertex is (2, 3).

*y* = (*x* − 2)^{2} + 3

The equation for a cubic graph is *y* = (*x* − *h*)^{3} +*k*.

*y* = (*x* − 2)^{3} + 3

Notice that the parabola opens downs and is steeper.
