Determine which lines, if any, are parallel or perpendicular. Explain. Line a: 2x−7y=14
Line b: y=72x−8
Line c: 2x+7y=−21Write a piecewise function for the graph.

domain is all the x values included in the

0 ≤ x ≤ 2

range is all the y values of the graph

-2 ≤ y ≤ 2

***keep in mind that there are different ways to show domain and range

hope this !
