WebSolve a rational inequality. Step 1. Write the inequality as one quotient on the left and zero on the right. Step 2. Determine the critical points–the points where the rational expression will be zero or undefined. Step 3. Use the critical points to divide the number line into intervals. Step 4. Test a value in each interval. WebThe solution of an inequality is the set of all numbers which satisfy the inequality. This set may have in nitely many numbers and may be represented by an interval or a number of intervals on the real line. Example The solution to the inequality 2x+ 1 3 is the set of all x 1. 3 2.5 2 1.5 1 0.5 Ð 1 Ð 2 Ð 3 Ð 3 Ð 2 Ð 1 1
