Question
Part I
![**Part I:**
**Dali's Target**
Consider the following contour map of a continuous function \( f(x, y) \):
![Contour Map of Function](path/to/your/image.jpg)
The contour map shows level curves for the values 10, 20, and 30 of the function \( f(x, y) \). The x-axis ranges from 0 to 10 and the y-axis ranges from 0 to 12.
1. **For approximately what values of \( y \) is it true that \( 10 \leq f(5, y) \leq 30 \)?**
2. **Estimate \( f(2, 4) \).**
3. **Estimate \( f(5, 8) \).**
4. **How many values satisfy \( f(7, y) = 20 \)?**
5. **How many values of \( x \) satisfy \( f(x, 8) = 20 \)?**
### Graph/Diagram Description
The contour map (or level curve map) shows the graphical representation of the function \( f(x, y) \) over the x-y plane. The contour lines represent places where the function \( f(x, y) \) has constant values.
- The contour line labeled 30 encloses the highest region of the graph.
- The contour line labeled 20 surrounds the area covered by the 30 level curve, indicating a lower value than the central region.
- The contour line labeled 10 encompasses both the 20 and 30 level curves, indicating that the function value is 10 along this outermost boundary.
In this map:
- Between each pair of consecutive contours, the function's value transitions smoothly.
- The concentration and spacing of contour lines help in understanding the gradient and slope of the terrain represented by the function.
**Analysis and Answers:**
1. **For approximately what values of \( y \) is it true that \( 10 \leq f(5, y) \leq 30 \)?**
Observing the contour map, for \( x = 5 \), the possible values of \( y \) that satisfy the given condition fall between 4 and 8.
2. **Estimate \( f(2, 4) \).**
At the point \( (2, 4) \), we are outside the contour line labeled 10, so we can estimate \( f(2](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fc3acae65-05d5-4940-8762-2c9a874e450a%2F583dde44-d004-41fd-ba22-77290d9a166b%2Fgmp91se_processed.jpeg&w=3840&q=75)
