**Graph Title:** Estimating Areas Under the Curve Using the Left Riemann Sum \( L_8 \)

**Description of the Graph:**
The graph represents a continuous function plotted on a Cartesian plane, with the x-axis ranging from -1 to 8 and the y-axis spanning approximately from -1 to 2. The function displays various peaks and troughs, indicating changes in direction and magnitude of the slope.

**Key Features:**
1. **X-Axis:** Labeled with numerical values at intervals of 1. The interval starts at -1 and ends at 8.
2. **Y-Axis:** Labeled with numerical values at intervals of 1, ranging from -1 to 2.
3. **Function Behavior:** 
   - Initially increases from the x-value of -1, then decreases slightly beyond 1.
   - Exhibits a sharp increase reaching a higher peak followed by a rapid decline to a low trough, and finally ascends again.
4. **Curve:** The curve moves smoothly through several cycles, representing changes in rate over the interval.

**Objective:**
Estimate the area under the curve by computing the left Riemann sum \( L_8 \). This method involves summing up the areas of rectangles under the curve using the left endpoints for height estimation.

**User Interaction:**
A checkbox is available for \( L_8 \) followed by a "help (numbers)" option to provide guidance on calculations or estimations.

This visual aid helps in understanding how to approximate the area under the curve using the left Riemann sum, illustrating the importance of partitioning intervals and using endpoint values for estimation.
