Evaluating an exponential function
The function gives the value of a home in dollars in the year 1980 + t. What was the value of the home in 1988? Round your answer to the nearest whole dollar amount and give units.

You would evaluate for t=8. The units should be dollars.
Your function should look like f(t)=Ke^t

So would the answer be 95850?

I didn't see the original function so I can't tell; I don't know the price in 1980 or the rate of appreciation.

This part, "The function gives ..." seems to be referring to a specific function. Is there one given in the text?
You can start a new thread if this gets too long.
BTW, you should be aware that there is both a discrete and continuous version for exponential functions.
We can use A=Pe^(rt) or A=P(1+r)^t.
The first is the continuous and the second is the discrete. They will give slightly different values, but both are used. I'm not sure which your text expects you to use.
