![### Educational Content
#### Graphs
The image contains two graphs that are mirror reflections across the y-axis. Both graphs are plotted on a coordinate plane with x-axis ranging from -1.5 to 1.5 and y-axis from -15 to 5. The left graph shows a curve starting at a higher y-value and declining as x increases, while the right graph is a mirrored version, starting lower on the y-axis and inclining as x increases. Exact values of the curves are not specified.
#### Mathematical Problems
1. **Problem 4**:
**Description**:
- **Title**: SALGTRIG4 4.2.023 (0/20 Submissions Used)
