Final answer:
To find the horizontal tangent line, you need to find the derivative of the function, set it equal to zero, and solve for the x-values.
Step-by-step explanation:
To find the horizontal tangent line, we need to find the derivative of the function and set it equal to zero. The derivative represents the slope of the tangent line at any given point on the graph. When the derivative is zero, it indicates that the tangent line is horizontal.
- Find the derivative of the function.
- Set the derivative equal to zero and solve for the x-values.
- Plug the x-values into the original function to find the corresponding y-values.
These x-values and y-values will give you the coordinates of the points where the horizontal tangent line intersects the curve.
