To estimate the instantaneous rate of change at \( x = 1 \) for the given graph, we need to find the slope of the tangent line to the curve at that point.

### Step-by-Step Solution:
1. **Identify the Point**: The graph shows a curve, and we need to find the y-coordinate of the curve at \( x = 1 \). From the graph, it looks like the point on the curve at \( x = 1 \) is approximately \((1, 3)\).

2. **Draw the Tangent Line**: To find the instantaneous rate of change at \( x = 1 \), visualize a line that just touches the curve at this point without crossing it. This line is the tangent line at \( x = 1 \).

3. **Estimate the Slope**: To estimate the slope of this tangent line:
   - Pick two points on the tangent line that are easy to read from the graph. Let's say the tangent line crosses the y-axis at \( (0, 4) \) and another point at \( (2, 2) \).
   - Use the slope formula: 
     \[
     \text{Slope} = \frac{y_2 - y_1}{x_2 - x_1} = \frac{2 - 4}{2 - 0} = \frac{-2}{2} = -1
     \]

4. **Estimate**: The estimated slope of the tangent line (and thus the instantaneous rate of change of the function at \( x = 1 \)) is approximately \(-1\).

### Conclusion:
The instantaneous rate of change at \( x = 1 \) is approximately \(-1\).
