Verify that the tangent line is horizontal.
Answer to Problem 68E
Tangents drawn on the function
Explanation of Solution
Given information:
Use the function and its derivative to determine any points on the graph of
Calculation:
Consider the function,
The slope of the function or the derivative is
The slope of the tangent drawn on the function
So, the slope will be
Now,
When,
When,
So, the points at which the function
