The point (4,-2) is the vertex of the graph of a quadratic function. The points (8,6) and (2,0) also fall on the graph of the function. Complete the graph of this quadratic function by first finding two additional points on the graph. Part A: What is the y-intercept of the graph?

Part B: What are the x-intercepts?

Part C: Find the interval on which the rate of change is always positive.

Part D: What is a sign of the leading coefficient for this quadratic function? How do you know?

Which represents the inverse of the function f(x) = 4x? h(x) = x + 4 h(x) = x – 4 h(x) = x h(x) = x

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.
