Im not sure how to put { x l -6 < x < 12 } as a graph

Kayla,

The statement is describing a set, that is a set that x belongs to. Note that because the upper and lower limits (12 and -6 respectively) are specified with < and > signs the set is open at the upper and lower limits. In other words the set does not include 12 or -6.

I would graph this as a bold line between -6 and 12 with a open circle (like an O) at each end to indicate the open set. The bold line would run along the x axis.

The verbal descriptin would be: " All x values greater than -6 but less than 12". (Note: this does not include -6 or 12)

Note: Because no Y or additional dimensions are specified in the statement, I treat this as a one dimensional, X, problem.
