![Check Mark](/static/check-mark.png)
Answer to Problem 39E
No vertical line could be drawn that intersects the given curve at more than one point. So, the given curve is 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.
No vertical line could be drawn that intersects the given curve at more than one point.
Conclusion:
In the above figure a vertical line which intersects the given curve at exactly one point. No vertical line could be drawn that intersects the given curve at more than one point. So, the given curve is not the graph of a function.

In the previous part, we found the average rate of change for several intervals of decreasing size starting at x = 5. The instantaneous rate of change of fat x = 5 is the limit of the average rate of change over the interval [x, x + h] as h approaches 0. This is given by the derivative in the following limit. lim h→0 - f(x + h) − f(x) h The first step to find this limit is to compute f(x + h). Recall that this means replacing the input variable x with the expression x + h in the rule defining f. f(x + h) = (x + h)² - 5(x+ h) = 2xh+h2_ x² + 2xh + h² 5✔ - 5 )x - 5h Step 4 - The second step for finding the derivative of fat x is to find the difference f(x + h) − f(x). - f(x + h) f(x) = = (x² x² + 2xh + h² - ])- = 2x + h² - 5h ])x-5h) - (x² - 5x) = ]) (2x + h - 5) Macbook Proarrow_forward
