\(24\left(\frac{1}{2}\right)^{\frac{t}{30}}\)

An exponential function representing the decay or growth of a quantity, where 24 is the initial value, \(\frac{1}{2}\) is the base of the exponent signifying decay, and \(\frac{t}{30}\) is the exponent indicating time or another variable at which the decay occurs.
