Solve the problem.A wildlife researcher is monitoring a black bear that has a radio telemetry collar with a transmitting range of 18 miles. The researcher is in a research station with her receiver and tracking the bear's movements. If we put the origin of a coordinate system at the research station, what is the equation of all possible locations of the bear where the transmitter would be at its maximum range?
A. x2 + y2 = 324
B. x2 + y2 = 18
C. x2 + y2 = 36
D. x2 - y2 = 18

Answer the problem.Use the following function and a graphing calculator to answer the questions.f(x) = 
+ 0.9 sin x, [0, 2?]a). Plot the function over the interval to see its general behavior there. Sketch the graph below.
b). Find the interior points where f' = 0 (you may need to use the numerical equation solver to approximate a solution). You may wish to plot f' as well. List the points as ordered pairs (x, y).c). Find the interior points where f' does not exist. List the points as ordered pairs (x, y).d). Evaluate the function at the
endpoints and list these points as ordered pairs (x, y).e). Find the function's absolute extreme values on the interval and identify where they occur. What will be an ideal response?
