Describe the behavior of the graph shown below. A. The graph is increasing when x > 2.

B. The graph is increasing for all values of x.

C. The graph is decreasing for all values of x.

D. The graph is increasing when x > 0.

Determine whether the following statements are true and give an explanation or counterexample. bold a. when using the shell method, the axis of the cylindrical shells is parallel to the axis of revolution. bold b. if a region is revolved about the y-axis, then the shell method must be used. bold c. if a region is revolved about the x-axis, then in principle it is possible to use the disk/washer method and integrate with respect to x or the shell method and integrate with respect to y.

Which equation represents a direct linear variationa. y=x2b. y=2/5xc. y=1/xd. y=x+3

Measure a and b and find their sum. how are the angles related?
