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 |
