Answer:

$v = 400000(2^\wedge d)$

Step-by-step explanation:

Given

$Initial\ Value = \$400000$

$Rate = doubles$ per decade

Required

Determine the equation of the function

The information given shows that the function is exponential and will be calculated using:

$v = ab^d$

Where:

a = Initial Value = 400000

b = rate = 2

d = number of decades

v = the current value of the home

So, we have:

$v = 400000* 2^\wedge d$

$v = 400000(2^\wedge d)$
