7. Domain and Range of Graphs
Domain = x
What values of x are part of the graph?
Range = y
What values of y are part of the graph?

8. Cube Root Function

9. Rules for Graphing Cube & Square Roots
1. Sketch the graph of:
Shift h units horizontally and k units
vertically
3. What does the a do to the graph?

11. Reminder:

12. Homework
P.434 #22-48 evens
Use calculator to get general graph, then shift.
Sketch BOTH graphs using graph paper
Must label the coordinate of the vertex of the graph.
State the domain and range of each graph in interval notation!
