Identify each function as modeling either exponential growth or exponential decay. What percent of increase or decrease does the function model? \(y=7.3(0.8)^x\)

expert advice

Identify each function as modeling either exponential growth or exponential decay. What percent of increase or decrease does the function model? \(\displaystyle{y}={0.1}{\left({1.7}\right)}^{{x}}\)

Identify each function as modeling either exponential growth or exponential decay. What percent of increase or decrease does the function model? \(y=0.32(0.99)^x\)

Tell whether the function represents exponential growth or exponential decay. Identify the percent increase or decrease. Then graph the function. \(\displaystyle{f{{\left({x}\right)}}}={\left({\frac{{{1}}}{{{3}}}}\right)}^{{x}}\)

Tell whether the function represents exponential growth or exponential decay. Identify the percent increase or decrease. Then graph the function. \(f(x)=\left(\frac{1}{3}\right)^{x}\)
