The function m, defined by m (h) = 300 - (3), represents the amount of a medicine, in milligrams, in a patient's body. h represents the number of hours after the medicine is administered. 1. What does m(0.5) represent in this situation? 2. This graph represents the function m. Use the graph to estimate m(0.5). 350 medicine in body (milligrams) 300 250 200 150 100 50 1 2 3 time (hours) 4 5 6 3. Suppose the medicine is administered at noon. Use the graph to estimate the amount of medicine in the body at 4:30 p.m. on the same day.
