In 2012 the average cost of a house in San Francisco was $521,000. In 2016 the average cost of a house in San Francisco was $821,000. Create an exponential model for the value of a house in San Francisco as a function of time in years since 2012 and use your model to predict what the value of the average house in San Francisco will be in 2025. You can choose to create a model in the form f (t) = A,et or in the form f(t)= Ca'. Show all of your work. Round all values to 3 decimal places.
