The x y-coordinate plane is given. The curve labeled y = f(x) enters the window in the second quadrant, goes down and right, crosses the x-axis at approximately x = −3.8, passes through the approximate point (−3, −1.2), changes direction at the approximate point (−2, −1.7), goes up and right, passes through the approximate point (−1, −1.4), crosses the y-axis at approximately y = −0.5, crosses the x-axis at approximately x = 0.4, passes through the approximate point (1, 1.6), changes direction at the approximate point (2, 3.3), goes down and right, passes through the approximate point (3, 2.6), and exits the window in the first quadrant.

The curve described follows a path through various key points and changes direction at specific locations. Here's a step-by-step analysis of the curve \( y = f(x) \):

1. **Entering from the second quadrant**: The curve enters from the second quadrant, indicating that for large negative values of \( x \), the function \( f(x) \) is positive, but it begins to decrease as it moves toward the right.

2. **Crossing the x-axis at \( x \approx -3.8 \)**: The curve crosses the x-axis around \( x = -3.8 \), meaning \( f(x) = 0 \) at that point. This is a root of the function, where the curve changes sign.

3. **Passing through the point \( (-3, -1.2) \)**: As the curve continues, it goes through the point \( (-3, -1.2) \), indicating that the value of the function at \( x = -3 \) is approximately \( f(-3) = -1.2 \). The function is decreasing here.

4. **Changing direction at \( (-2, -1.7) \)**: The curve reaches a local minimum at \( (-2, -1.7) \), which suggests that the slope is zero at this point, and the curve starts to rise afterward. This is a critical point where the function changes from decreasing to increasing.

5. **Passing through \( (-1, -1.4) \)**: After the minimum, the function increases as it passes through \( (-1, -1.4) \).

6. **Crossing the y-axis at \( y \approx -0.5 \)**: The curve crosses the y-axis at approximately \( y = -0.5 \), meaning \( f(0) \approx -0.5 \). This is the y-intercept.

7. **Crossing the x-axis at \( x \approx 0.4 \)**: The curve crosses the x-axis again at \( x \approx 0.4 \), indicating another root of the function.

8. **Passing through \( (1, 1.6) \)**: The curve rises and passes through \( (1, 1.6) \), meaning \( f(1) = 1.6 \).

9. **Changing direction at \( (2, 3.3) \)**: The curve reaches a local maximum at \( (2, 3.3) \), where the slope is zero, and it starts to decrease after this point. This is another critical point, but this time a local maximum.

10. **Passing through \( (3, 2.6) \)**: After the maximum, the curve decreases and passes through \( (3, 2.6) \).

11. **Exiting through the first quadrant**: Finally, the curve exits the window in the first quadrant, meaning it continues to decrease but remains in positive \( y \)-values as \( x \) increases.

### Summary of Critical Points:
- \( x \approx -3.8 \) (crossing x-axis)
- Local minimum at \( (-2, -1.7) \)
- Local maximum at \( (2, 3.3) \)
- \( x \approx 0.4 \) (crossing x-axis)

These details suggest that the function has at least two roots, a local minimum and maximum, and possibly multiple inflection points.
