4-91.
  1. Use the point (h, k) to help you write a possible equation for each graph shown below. Homework Help ✎

    1. graph

    2. graph

    3. graph

Remember that y = (xh)2 + k.

Notice that the vertex is (2, 3).

y = (x − 2)2 + 3

The equation for a cubic graph is y = (xh)3 +k.

y = (x − 2)3 + 3

Notice that the parabola opens downs and is steeper.
