Example 2: Given the function ( ) , find the zeros, then find the intervals where the function is positive and negative (express in interval notation). Example 3: Given the function ( ) , find the zeros, then find the intervals where the function is positive and negative (express in interval notation). Example 4: Given the function ( ) , find the zeros, list any restrictions on the domain, then find the intervals where the function is positive and negative (express in interval notation).
Solving nonlinear inequalities: 1. set one side of the inequality to zero. 2. combine like terms, then factor the other side. 3. find the values that make each factor zero (including restrictions). 4. set-up a number line using the values from step 3. 5. find the intervals that satisfy the inequality by using test values.
