The value of a home in 2015 was $400,000. Its value has been doubling each decade.

If v is the value of the home, in dollars, write an equation for v in terms of d, the number of decades since 2015.

What is v when d = -1? What does this value mean?

What is v when d = -3? What does this value mean?
