Question

Solve the inequality and graph the solution.
2n–2<2
To draw a ray, plot an endpoint and select an arrow. Select an endpoint to change it from closed to open. Select the middle of the ray to delete it.

Answer 1

Solve: 2n − 2 < 2
Add 2 to both sides: 2n < 4
Divide by 2: n < 2

Solution: n < 2 (interval notation: (−∞, 2))

Graph: an open circle at 2 with a ray pointing left (all numbers less than 2).
