Unformatted text preview: 1 Procedure: 1. Find all number(s) where f ( x ) is discontinuous and all zero(s) of f ( x ). 2. Plot the number(s) found in step 1 on a real number line, which divide the number line into intervals. 3. Select a test number in each interval determine in step 2 and evaluate f ( x ) at each test number to determine whether f ( x ) is positive or negative in each interval. 4. Construct a sign chart using the real number line in step 2. This will show the sign of f ( x ) on each interval. Example 3. Solve each of the following inequalities: (a) ( x1)( x + 2)( x + 3) > (b) x 21 x3 ≤ 2...
