4-91.

Use the point $\left(h,k\right)$ to help you write a possible equation for each graph shown below.

1. Remember that $y=(x−h)^2+k$.

Notice that the vertex is $(2,3)$.

$y=(x−2)^2+3$

1. The equation for a cubic graph is $y=(x−h)^3+k$.

$y=(x−2)^3+3$

1. Notice that the parabola opens downs and is steeper.
