Question

a scientist uses the equation shown below to predict the future population of a species. in the equation, y represents the estimated population and t represents the number of years. y = 150 * 4^t

Explanation:

Step1: Analyze the equation type

The equation $y = 150\cdot4^{t}$ is an exponential - growth equation of the form $y = a\cdot b^{t}$, where $a = 150$ is the initial value and $b = 4$ is the growth factor.

Answer:

The equation $y = 150\cdot4^{t}$ is an exponential - growth equation used to predict the population of a species over time.
