The increase in a person’s body temperature T(t), above 98.6ºF, can be modeled by the function , where t represents time elapsed. What is the meaning of the horizontal asymptote for this function?
A
The horizontal asymptote of y = 0 means that the person’s temperature will approach 98.6ºF as time elapses.B
The horizontal asymptote of y = 0 means that the person’s temperature will approach 0ºF as time elapses.C
The horizontal asymptote of y = 4 means that the person’s temperature will approach 102.6ºF as time elapses.D
The horizontal asymptote of y = 4 means that the person’s temperature will approach 4ºF as time elapses.64
