Final answer:
An exponential function can be used to model the population growth of Salt Lake City.
Step-by-step explanation:
An exponential function is used to model the growth or decay of a quantity that increases or decreases exponentially over time. In this case, we can use an exponential function to model the population of Salt Lake City. If the population doubled every 10 years, we can use the formula P(t) = P0 * (1 + r)^t, where P(t) is the population after t years, P0 is the initial population, r is the growth rate, and t is the time in years.
In this case, the initial population is the population in the starting year, and the growth rate is determined by the doubling time. So the equation that best defines the function would be P(t) = P0 * (1 + 0.07)^t, where P0 is the population in the starting year, and t is the number of years after the starting year.
For example, if the population of Salt Lake City in the starting year was 100, then the equation would be P(t) = 100 * (1 + 0.07)^t.
