Answer 5

The following function represents the value of a house, in dollars, after x years:

f(x) = 242,000(1.04)x

What does 242,000 represent?



The present value of the house
The value of the house after x years
The increase in the value of the house each year
The increase in the value of the house after x years

A?

Answer 6

Is 1.04 raised to the x power?

Answer 7

Yes.

Answer 8

I just know, i think it should be an exponential function

Answer 9

when x = 0

y = 242000(1.04)^0

a number to the zero power = 1

y(0) = 24000

Answer 10

So is the answer A.. or?

Answer 11

the 242000 represents the initial value of the house at time zero

Answer 12

so i guess A would be it, if the present is considered time t=0,, then yes it is the present value of the house
