The procedure to solve a polynomial or rational inequality may be applied to all inequalities of the form f ( x ) > 0 , f ( x ) < 0 , f ( x ) ≥ 0 , and f ( x ) ≤ 0 . That is, find the real solutions to the related equation and determine restricted values of x . Then determine the sign of f ( x ) on each interval defined by the boundary points. Use this process to solve the inequalities in Exercises 109-120. 2 x − 6 − 2 < 0
