Solve.A painting was sold in 1985 for $ 2 million. The painting was then resold in 1996 for $ 6 million. Assume that the painting's value increases exponentially. Find the exponential growth rate k, and determine the exponential growth function, assuming V0 = 2. (Round decimals to three places.)
A. k = 0.1; V(t) = 2e0.1, where V(t) is in millions and t is the number of years after 1985. B. k = 0.1; V(t) = 2e0.1t, where V(t) is in millions and t is the number of years after 1985. C. k = 0.1; V(t) = 2e0.1t, where V(t) is in millions and t is the number of years after 1997. D. k = 0.092; V(t) = 2e0.092t, where V(t) is in millions and t is the number of years after 1985.
