To state:
Using the vertical line test, whether the given curve is the graph of function.

Answer to Problem 37E
There exists a vertical line which intersects the given curve at more than one point. So, the given curve is not the graph of a function.
Explanation of Solution
Given:
The curve:
Concepts Used:
The vertical line test to determine whether a curve is the graph of a function states: if every vertical line in the
Calculations:
Draw a vertical line through the given curve at a place where it looks likely to intersect the curve at more than one points.
Conclusion:
In the above figure it is shown that there exists a vertical line which intersects the given curve at more than one point. So, the given curve is not the graph of a function.

- A 20 foot ladder rests on level ground; its head (top) is against a vertical wall. The bottom of the ladder begins by being 12 feet from the wall but begins moving away at the rate of 0.1 feet per second. At what rate is the top of the ladder slipping down the wall?
