Question: Graph the system of inequalities
| Foundations |
|---|
| 1) What do the graphs of , and look like? |
| 2) Each graph splits the plane into two regions. Which one do you want to shade? |
| Answer: |
| 1) The first graph looks like a V with the vertex at (0, 1), the latter is a circle centered at the origin with radius 3. |
| 2) Since the Y-value must be less than , shade below the V. For the circle shde the inside. |
Solution:
| Step 1: |
|---|
| The zeros of the left hand side are , 1, and 4 |
