A-P(1+ =)". The equation for compound interest is A-A where Pis the initial amount invested, ris the interest rate as a decimal, n is the number of times compounded annually, and t is the number of years. A person is investing $1000 at an interest rate of 12% interest for 25 years, and is curious how much difference the number of compounds (n) increases the value of the account after 25 years. She created the function: A(n) 1000 n 25 What would best describe an appropriate domain of the function? The set of Integers (i.e. {..... -2, -1, 0, 1, 2, ......}) The set of Natural Numbers (i.e. {1, 2, 3, 4, ...)}) The set of All Real Numbers (R) where 20
