Given the following exponential function, identify whether the change represents growth or decay, and determine the percentage rate of increase or decrease.y, equals, 4600, left bracket, 0, point, 9, 6, right bracket, to the power xy=4600(0.96) x

Given the following exponential function, identify whether the change represents growth or decay, and determine the percentage rate of increase or decrease per unit of xx, to the nearest tenth of a percent.y, equals, 4, start superscript, minus, 2, x, end superscripty=4 −2x

Instructions: Graph the following function. Then, state whether the function represents exponential growth or decay.y=(45)x𝑦=(45)𝑥This function is exponential

At the beginning of a population study, a city had 300,000 people. Each year since, the population has grown by 5.8%.Let t be the number of years since start of the study. Let y be the city's population.Write an exponential function showing the relationship between y and t.

Percentage increase and decrease

The projected value of an investment is modeled by the exponential function V(t)=30,000(1.125)t𝑉(𝑡)=30,000(1.125)𝑡, where V(t)𝑉(𝑡) is the total value after t𝑡 years. What is the percent increase each year for the investment?
