Q. Does the function model exponential growth or decay?\newlineg(t)=1.70.8t g(t)=1.7 \cdot 0.8^{t} \newlineChoose 11 answer:\newline(A) Growth\newline(B) Decay
  1. Identify base: Step 11: Identify the base of the exponential function. In the function g(t)=1.7×0.8tg(t)=1.7\times 0.8^{t}, the base of the exponent is 0.80.8.
  2. Determine growth or decay: Step 22: Determine if the base is greater than 11 or less than 11. If the base is greater than 11, the function models exponential growth. If the base is less than 11, the function models exponential decay.
  3. Compare base to 11: Step 33: Compare the base 0.80.8 to 11. Since 0.80.8 is less than 11, the function g(t)=1.7×0.8tg(t)=1.7\times 0.8^{t} models exponential decay.
  4. Choose correct answer: Step 44: Choose the correct answer based on the analysis. Since the base is less than 11, the function represents decay, not growth.
