Chester was running an experiment on a sample of 400 grams of a radioactive isotope with a half-life of 1 hour. He was determining the amount of isotope remaining after various elapsed time intervals. Using his collected data, Chester formulated the graph below to model the amount of radioactive isotope remaining after an elapsed time in hours. What is the y-intercept and asymptote?
y-intercept: (0,400); asymptote: y=0
y-intercept: (0,0); asymptote: y=4
y-intercept: (0,7); asymptote: x=0
y-intercept: (0,10); asymptote: y=4
