a. Find the open intervals on which the function shown in the graph is increasing and decreasing. b. Identify the function's local and absolute extreme values, if any, saying where they occur.

The graph shows the height, in meters, of an eagle in terms of its time, in seconds, in flight. a. Is the eagle’s height a function of time? Use the graph to explain why or why not. b. On which interval is the function decreasing? Describe what this means in practical terms. c. On which intervals is the function constant? What does this mean for each of these intervals? d. On which interval is the function increasing? What does this mean?

b. Tell if the piece-wise function is continuous on the given interval. Put a CHECK MARK AFTER the interval if it is continuous. Put an EX MARKX AFTER the interval if it is discontinuous. [-3, -2] (0, 1) [-4, -3) [-1, 1) (1, 3] (2,4] -1 t Using the graph above, write 1 interval where the function is continuous and 1 interval where it is discontinuous.

Let's simulate the process of constructing a matrix for a 3D transformation that rotates 13 degrees about the axis n = [0.3, 0.2, 0.5]. First step: is the vector n a unit vector? (on the answers, 0.3^2 means 0.3-squared, and so on) O Yes, since 0.3 +0.2 + 0.5 = 1 O No, since 0.3^2 +0.2^2 + 0.5^2 1 O No, since 0.3^2 +0.2^2 + 0.5^2 = 1
