Derivative review question and answer...
MTH 202
Prof. Sundstrom Derivative Review Problems
1. The graph to the right contains the graph of a function y f x and several points and lines. For each of the quantities below, state whether it is represented on the graph by a length or by a slope. Then using the points represented by letters, make clear exactly which length or slope represents the quantity. Note: The letters, P, Q, R, etc. represent points of intersections of lines and/or curves. The line QU is tangent to the graph of y f ( x) at Q and the line VT is tangent to the graph of y f ( x) at T.

4. The graph to the right is a graph of the equation ln xy 2 x .
The point 1, e 2 is shown on the graph. a. Use implicit differentiation to determine a dy . (Your answer should be formula for dx a formula in terms of x and y.)
b. Use your result from Part (a) to determine the equation of the line tangent to the graph of the equation ln xy 2 x at the point 1, e 2 .

5. For time t measured in seconds, the graph to the right shows the vertical velocity v t (in feet per second) of an object. (The upward direction is the positive direction and the downward direction is the negative direction.) The object started from ground level [ s 0 0 , where s t is the vertical altitude of the object in feet].
The graph consists of two straight lines and two quarter circles of radius 20. a. Over what intervals is the vertical altitude s t increasing? b. At what time was the greatest vertical altitude attained? c. What is the value of

v t dt ?
d. What was the average vertical velocity of the object between 0 and 100 seconds?...
