13. As a newborn in 1949, Hal's grandparents gave him a gift of $1000 in a savings account with a simple interest rate of 4% per year. As Hal aged, his gift grew and he withdrew the money so he could transfer it to his sons. The growth of his account can be modeled by the equation y = 1000(1.04)* where y is the value of the account and x is the number of years. What are some of the possible limitations of the parameter in this scenario in relation to the value of the account? More than one answer may be correct; check all that apply. Hal's birthdate is a parameter, because that's when the money was deposited. The date of withdrawal is a parameter, because that's when the account growth would stop. The number of sons Hal has is a parameter, because we need to know how to split the inheritance. Hal's age is a possible parameter, because he would have to withdraw the money while still alive. None of these statements are possible parameters.
