The graph of the function displays the height in yards of a terrain traveled by a motorcyclist at specific mile markers along a highway. Use the graph to find each of the following. (a) Determine the domain and range. (Enter your answers using interval notation.) domain range Height of Terrain (yards) (b) Determine the height at mile marker 6. y = (f) 900 800 700 600 500 400 300 200 100 0 0 2 4 6 8 10 12 14 16 Mile Marker (c) Determine the height at mile marker 8. y = X (d) At what mile markers is the terrain at sea level? (Enter your answers as a comma-separated list.) (e) Determine the y-intercept. (x, y) = Between mile markers 4 and 12, how many times is the height of the terrain 100 yards?
