If coordinates are (2,-63); is the y coordinate considered for deciding the maxima or minima?
n if its -ve then its minima n if +ve then maxima?

another question...

Jane's bank balance put $1000 into a savings bank account for her on each birthday from her 10th to her 18th. The account pays interest at 6% for each complete year that the money is invested. How much money is in the account on the day after her 18th birthday?
