Some banks charge a fee on savings accounts that are left inactive for an extended period of time. The equation y = 5000(0.98)^x represents the value, y, of one account that was left inactive for a period of x years. What is the y-intercept of this equation and what does it represent?

• 0.98, the percent of money in the account initially

• 0.98, the percent of money in the account after x years

• 5000, the amount of money in the account initially

• 5000, the amount of money in the account after x years
