The problem displayed on your screen is asking you to approximate the area under a curve from \( x = 3 \) to \( x = 7 \) using a Left Endpoint approximation with 4 subdivisions.

To approach this, here’s a step-by-step solution process for a Left Endpoint approximation:

### Steps
1. **Determine the width of each subdivision (Δx):**
   - The interval is from \( x = 3 \) to \( x = 7 \), so the total width is:
     \[
     \Delta x = \frac{7 - 3}{4} = 1
     \]
2. **Identify the Left Endpoints for each subdivision:**
   - Since we’re dividing the interval into 4 parts, and using Left Endpoint, the x-values for the left endpoints are:
     \[
     x = 3, 4, 5, \text{ and } 6
     \]
3. **Evaluate the function at each Left Endpoint:**
   - Assuming the function is given as \( f(x) \) (though not specified in the image, let’s assume the graph is of some function \( f(x) \)), find \( f(3) \), \( f(4) \), \( f(5) \), and \( f(6) \).
   
4. **Calculate the approximate area:**
   - The approximate area \( A \) is:
     \[
     A \approx \Delta x \times [f(3) + f(4) + f(5) + f(6)]
     \]
   - Substitute the values you obtain from the graph for \( f(3) \), \( f(4) \), \( f(5) \), and \( f(6) \).

If you can see the specific values from the graph for each function value, substitute them to calculate the final approximation.

Would you like further clarification on any step, or help in reading values directly from your graph?

Here are some related questions for further understanding:
1. How does Left Endpoint differ from Right Endpoint or Midpoint approximations?
2. What would be the effect of increasing the number of subdivisions on the approximation accuracy?
3. How is the width of each subdivision calculated if the interval length or number of subdivisions changes?
4. How do Left Endpoint approximations relate to definite integrals?
5. What other methods are there for approximating areas under curves?

**Tip:** When approximating areas, more subdivisions generally yield a result closer to the actual area under the curve.
