The function below gives the body concentration, in parts per million, of a certain dosage of medication after 't' hours. Find the horizontal asymptote and interpret what it means. y(t) = 0.8t+1000 51+4 t? 15 1) The horizontal asymptotte is y = 0.8 and this means that there are 0.8 parts per million of the medication dosage left in the body as t approaches infinity. 2) The horizontal asymptote is y = 0 and this means that there are 0 parts per million of the medication dosage left in the body as t approaches infinity. 3) The horizontal asymptote is y = 0.16 and this means that there are 0.16 parts per million of the medication dosage left in the body as t approaches infinity. 4) The horizontal asymptote is y = -0.8 and this means that there are -0.8 parts per million of the medication dosage left in the body as t approaches infinity.
