Is this exponential growth or decay? Explain using your understanding of the properties of exponents. (To type exponents, use the ^ key.)

Answer:

This is exponential decay. The negative exponent means the base is reciprocated, so N(t) = 300 · (1/2)^(t/8) = 300 · 0.5^(t/8). Because the base is less than 1, the function decays.
