Mark opened a savings account at his bank with a guaranteed annual interest rate of 5.0% for 5 years. If he deposits $10,000.00 into the account and the interest is compounded annually, the interest on the account is modeled by the function A = 10,000(1 + .05)t.What is the domain of this function in this context?

Question

Answer:

The domain of the function is all valid values of t.
Since t cannot be negative, the domain of t is all non-negative numbers, or
0 ≤ t < ∞
In interval notation, t=[0, ∞ )
