Graphing Square Root and Cube Root Functions

2. Square roots

3. Cube roots
Domain:
Range:
All real numbers
All real numbers

4. Graphs of Radical Functions
Tranformations:
The graph shifts h units horizontally and k units vertically.
The graph will stretch or compress and/or reflects depending on the a value.

5. Example 1 b) Describe how to obtain the graph of
a) Describe how to obtain the graph of
b) Describe how to obtain the graph of

6. Example 2: Graph the following functions, and then state the domain and range. Only use a calculator to check.
a) b) c) y x y x y x

7. Example 2: Graph the following functions, and then state the domain and range. Only use a calculator to check.
d) e) f) y x y x y x

8. Inequalities Graph using same method as other inequalities.
- Solid or dashed line???
- Shade above or below???
For square root functions: from endpoint, shade straight up/down.

9. Example 3
Graph. Then find domain.
a) b) y x y x
