Question
The graph of a differentiable function is shown on the closed interval . How many values of x in the open interval satisfy the conclusion of the Mean Value Theorem for ?
| A. One | |
| B. Two | |
| C. Three | |
| D. Four |
Hint :
The Mean Value Theorem guarantees the existence of at least one value of in the open interval at which the slope of the line tangent to the graph of equals the slope of the secant line on .
Explanation
The Mean Value Theorem (MVT) guarantees the existence of at least one value in the open interval at which the slope of the line tangent to the graph of equals the slope of the secant line on .
To determine how many values of x in the open interval satisfy the conclusion of the Mean Value Theorem, first connect the endpoints of the graph to draw the secant line.
Now count the number of times that a tangent line drawn to the curve is parallel to the secant line. Parallel lines have the same slope, so the slope of each tangent line must be equal to the slope of the secant line.
Note: It is not necessary to determine the exact values of the points of tangency.
Therefore, there are four values of x in the open interval (−2, 5) that satisfy the conclusion of the Mean Value Theorem for [−2, 5].
(Choice A) "One" may be a result of mistakenly assuming that there can only be one possible value of x that satisfies the conclusion of the Mean Value Theorem.
(Choices B and C) "Two" and "Three" may be a result of neglecting to include all the values of x where the tangent to the graph is parallel to the secant line.
Things to remember:
The Mean Value Theorem guarantees the existence of at least one value
in the open interval
at which the slope of the line tangent to the graph of
equals the slope of the secant line on .
Question
If f(x) = x sin x, which of the following does the second derivative test guarantee about the function f at x = 0 ?
| A. The function f has a relative minimum at x = 0. | |
| B. The function f has a relative maximum at x = 0. | |
| C. The second derivative test is inconclusive for the function f at x = 0. | |
| D. The function f does not meet the conditions of the second derivative test at x = 0, so the test cannot be applied. |
Explanation
The second derivative test can be applied to a function f at any x = c for which f′′(c) exists and f′(c) = 0.
To determine if the second derivative test can be applied to the given function at x = 0, first calculate f′(0). The given function is a product of functions, so differentiate with the product rule.
| Given function | |
| Apply product rule | |
| Differentiate | |
| Multiply and rearrange terms | |
| Plug in x = 0 | |
| Simplify |
The first derivative equals 0 at x = 0, so f has a critical point at x = 0. Now differentiate f'(x) and plug in x = 0 to see if the second derivative exists at x = 0.
| First derivative | |
| Apply product rule to first term | |
| Differentiate | |
| Multiply and rearrange terms | |
| Plug in x = 0 | |
| Simplify |
The second derivative exists at x = 0, and . Therefore, the second derivative test can be applied at x = 0.
The second derivative is positive, so the second derivative test states that f has a relative minimum at x = 0.
Question
A function f is decreasing and concave up on the interval [2, 4]. Which inequality gives the following values in increasing order?
I. f(3)
II. f(3.1)
III. The approximation of f(3.1) using the line tangent to f at x = 3
| A. I < II < III | |
| B. II < III < I | |
| C. III < I < II | |
| D. III < II< I |
Explanation
The function f is decreasing, so f(3.1) < f(3). The function f is concave up, so tangent line approximations underestimate values near the point of tangency. Therefore, the approximation of f(3.1) using the line tangent to f at x = 3 must be less than f(3.1).
Therefore, the inequality III < II < I lists the given values in increasing order.
