To explain: The reason that if a curve is symmetric about

Answer to Problem 36E
It fails the vertical line test as the vertical line meets the curve at two different points. So, the curve is not the graph of the function.
Explanation of Solution
Given information: For a curve to be symmetric about the
If a vertical line is drawn at the point
So, the curve fails the vertical line test.
Therefore, the curve symmetric about the
