The house had the appraised value of $70,000 in 1980 and $190,000 in 2000. Suppose that house's value V (in $ thousand) is exponential function of time t (in years since 1980).
i) Determine the formula for house's value as the function of time and determine annual percent increase in value
ii) Suppose the formula in part (a) remains valid after 2000, find value of house be in 2010?
