Question

Create an exponential function to represent a population of 50 insects that is growing at a rate of 7%. Which of the following functions is accurate?(1 point)

f(x)=50(1.7)^x


f(x)=50(0.93)^x


f(x)=50(0.07)^x


f(x)=50(1.07)^x

Answer 1

f(x) = 50(1.07)^x

Explanation: a 7% growth means multiply by 1 + 0.07 = 1.07 each time period. The others represent 70% growth (1.7), 7% decay (0.93), or a factor of 0.07.
