Question

Solve the inequality and graph the solution.
c
2
–1<1
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

I’ll assume the inequality is (c/2) − 1 < 1.

Solve:
(c/2) − 1 < 1
(c/2) < 2 (add 1 to both sides)
c < 4 (multiply both sides by 2)

Interval notation: (−∞, 4)

Graph: on a number line put an open circle at 4 and draw a ray/arrow extending left from 4 toward −∞.

If you meant a different expression (for example c^2 − 1 < 1), tell me and I’ll solve that one instead.
