### Finding Points of Horizontal Tangency

**Problem Statement:**
Use a graphing utility to graph \(f\) and \(f'\) over the given interval. Determine any points at which the graph of \(f\) has horizontal tangents. (Order your answers from smallest to largest \(x\), then from smallest to largest \(y\). Round your answers to three decimal places.)

**Given Functions and Interval:**
\[ f(x) = x^3 - 1.3x^2 - 0.97x + 1.41 \]
Interval: \([-2, 2]\)

**Solution:**
The potential points of horizontal tangency are evaluated, and their coordinates are shown below:

1. \((x, y) = \left( -0.282, 0 \right)\) - Incorrect
2. \((x, y) = \left( 1.148, 0 \right)\) - Incorrect

**Explanation of Diagram and Results:**
The image includes the following elements:

- A given polynomial function \(f(x)\).
- An instruction to use graphing utility software to plot the function and its derivative over a specified interval.
- Two evaluated points \((-0.282, 0)\) and \( (1.148, 0)\), each marked with a red cross (×), indicating that these points are incorrect for horizontal tangency.

To accurately determine the points of horizontal tangency:
- The derivative \(f'(x)\) should be computed.
- The roots of \(f'(x)\) (the \(x\)-values where \(f'(x) = 0\)) are found, ensuring all potential horizontal tangent points within the given interval are obtained.
