The function N(t) = (0.8t + 1000 ) / (5t+4), where t=>15 gives the body concentration N(t), in parts per million, of a certain dosage of medication after time t, in hours.
? Find the horizontal asymptote of the graph and complete the following statement: N(t) approaches ? as t approaches infinity.
This shows how to find the horizontal asymptote and limit of a function.
