Question

The increase in a person’s body temperature T(t), above 98.6ºF, can be modeled by the function T(t)=4t/t^2+1, where trepresents time elapsed. What is the meaning of the horizontal asymptote for this function?

Answer 1

the Temperature tends to remain at 98.6°F

Explanation:

Answer 2

The meaning of the horizontal asymptote is that the increase in a person's body temperature is a constant value when long time passes.

You can obtain that value by calculating the limit of the function when t → ∞:

4t
T(t) = ------------- => Lim T(t) when t → +∞ = 0.
t^2 + 1

That means that at long term the Temperature tends to remain at 98.6°F.
