Write the exponential growth function

Devise the exponential growth function that fits the given data, then answer the accompanying question. Be sure to identify the reference point (t = 0) and units of time. The current population of a town is 75,000 and is growing exponentially. If the population is projected to be 90,000 in 20 years, then what will be the population 30 years from now? What is the reference point (t = 0)? O the population in 20 years, 90,000 the current year the initial population, 75,000 What are the units of time? years O decades O people O percent Write the exponential growth function. y(t) = (Type an expression. Round coefficients to three decimal places as needed.)
