Researchers studied the population of a town over time and modeled the data using an exponential function.
-The initial estimated population was 48,000
-After the first year, the population of the town was 50,400.
If the population of the town continues to grow at this rate each year, which function can be used to model the population x years after the researchers began their study?

p(x)=50,4000(\frac{1}{48,000})^x

p(x)=48,000(\frac{50,400}{48,000})^x

p(x)=50,4000(\frac{50,4000}{48,000})^{x}

p(x)=48,000(\frac{1}{50,400})^x
