If you deposit $2500 into an account paying 11% annual interest compounded quarterly, how long until there is $4500 in the account?

answer: domain and range mean all possible values of x and y that could be substituted to the inequality. a solution means all possible values that make the inequality statement true. so while the range is still all real numbers, the solution is the shaded area, for which y will always be greater than the line of the function.
