The set of possible values of m is {5,7,9}. what is the set of possible values of k if 2k=m+3?

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.

all it means is function 3
