Answer:
1. domain: -6 ≤ x ≤ 7
range: -6 ≤ y ≤ 4
2. domain: 5 > x
range: -5 < y
Step-by-step explanation:
1. domain: the farthest number left that the line reaches is -6, while the farthest right is 7. due to the line being closed as well as the points being filled in, you use the less than or equal to sign.
range: the farthest number down that the line reaches is -6, while the farthest is goes up is 4. again, since the points are filled in, you use the "or equal to" sign.
2. domain: since the only plotted point is 5, and the point is not filled in, you would say that 5 is greater than x due to the direction that the line moves
range: the lowest part of the line touches -5 and only goes up from there, therefore y is greater than -5
