The temperature of a person during a certain illness is given by the following equation, where \( T \) is the temperature \( \left({ }^{\circ} \mathrm{F}\right) \) at time \( t \), in days. Find the relative extreme points and sketch a graph of the function. \( T(t)=-03 t^{2}+24 t+983,0 \leq t \leq 8 \)
