The limit as h approaches 0 of (e^(2+h)-e^2)/h = ?
the answer is e^2; explain how to get that?

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.
