Question

(h) Difference Equation Model for discrete-time systems Suppose that ylk balance of a savings account at the beginning of day k, and ulk] the amount deposited during day k. If interest is computed and added daily at a rate of +1001%), what is the balance at the beginning of day k +1? This describes the savings account as a discrete-time system on the time axis k. If the interest rate does not change with time, is the system time-invariant or time-varying? represents the MacBook Ai
