Given the parent function f(x)=x, which of the following is true about this graph?

b) the dogs need to shift their focus to human scent.

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.
