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?
Accepted Solution
A:
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, ∞ )
