### Understanding Left and Right Riemann Sums

In calculus, Riemann sums are an important method for approximating the total area under a curve. This educational page focuses specifically on left and right Riemann sums in the context of the exponential function \( y = e^x \).

#### Problem Statement

1. **Left Riemann Sum:**
   - Sketch \( y = e^x \) and represent the left Riemann sum with \( n = 2 \) to approximate the integral \(\int_{3}^{4} e^x \, dx\).
   - Expression for the sum without evaluation:  
     \[
     \text{Sum} = \text{\_\_\_} + \text{\_\_\_}
     \]

2. **Right Riemann Sum:**
   - On another sketch, represent the right Riemann sum with \( n = 2 \) approaching the same integral \(\int_{3}^{4} e^x \, dx\).
   - Expression for the sum without evaluation:  
     \[
     \text{Sum} = \text{\_\_\_} + \text{\_\_\_}
     \]

#### Key Questions

- **Which sum is an overestimate?**
  - A. The right Riemann sum  
  - B. The left Riemann sum  
  - C. Neither sum  

- **Which sum is an underestimate?**
  - A. The left Riemann sum  
  - B. The right Riemann sum  
  - C. Neither sum  

#### Explanation of Graph Requirements

In this exercise, you are asked to produce sketches of the function \( y = e^x \) over the interval from 3 to 4:

- **Left Riemann Sum:**  
  - Use rectangles where the height is determined by the value of the function at the left endpoint of each subinterval.
  - Since \( e^x \) is an increasing function, the left sum will underestimate the actual area under the curve.

- **Right Riemann Sum:**  
  - Use rectangles where the height comes from the value at the right endpoint of each subinterval.
  - This sum will overestimate the area because the function is increasing.

By understanding these concepts and how they apply to increasing functions like \( e^x \), you can approximate integrals more effectively and identify whether your Riem
