      b. 0 < < 5 states that x is any number between 0 and 5, without including the endpoints. c. x < -3 or x ≥ 2 states that the values of x are either less than -3 or greater than or equal to 2. We can express the solution set to a compound inequality by graphing on a number line, or using interval notation.
