The value of a house is 400,000 in 2015 and it doubles every decade. 1.If v is the value of the house, in dollars write an equation for v in terms of d, the number of decades since 2015.

Step-by-step explanation:

Given that,

The value of a house is 400,000 in 2015 and it doubles every decade.

Let v be the value of the house.

We need to find an equation for v in terms of d (the number of decades since 2015).

It shows that the function is exponential. So,

Where

a = Initial Value = 400000

b = rate = 2

d = number of decades

v = the current value of the home

So,
