Answer:

Step-by-step explanation:

The given exponential expression takes on the following form.

In this expression, a is the initial amount, b is the growth or decay factor, and x is the independent variable. If 0 < b < 1, then the expression represents decay, and if b > 1, then it represents growth.

Therefore, the base, 1.035, represents the growth factor which reveals the rate at which the account balance increases.
