8. A camera is mounted at a point 3000ft from the base of a rocket launching pad, the rocket rises vertically when launched, and the camera's elevation angle is continuously adjusted to follow the bottom of the rocket. a) Express the height x as a function of the elevation angle 0. b) Find the domain and range of the function in part (a) c) Plot the graph of the function in part (a) and use it to estimate the height of the rocket when the elevation angle is . Compare this to estimate the exact height
