Answer:
- y₁ = |x + 6| and y₂ = 25
Step-by-step explanation:
<u>Given inequality</u>
- |x+6| - 12 < 13
- |x+6| < 13 + 12
- |x+6| < 25
To solve this inequality graphically you need two graphs according left and right sides of inequality
<u>So the graphs should be:</u>
- y₁ = |x + 6| and y₂ = 25
See attached for the graph
