Write a section objective. 2. Explain how solving an equation can be thought of as the reverse of evaluating an expression. 3. What is a solution set? And what is the math notation for a solution set? Example 1: Solve 4x+7=39 and write the solution set. 4. How do you verify that the solution set is correct? 5. What is the proper notation for the solution set of an equation which has no solution? 6. What does it mean to say that 2 equations are equivalent? Example 2: Solve 3x+2 = 3x and write the solution set in two different formats. Example 3: Solve (2x-7)(x+6)=0 and write the solution set. Suppose the domain in example 3 were x int egers, what would the solution set be? Suppose the domain in example 3 were xnaturalnumbers, what would the solution set be? Example 4: Solve x 3 7 and write the solution set. 7. Copy the definition of extraneous solution and restate in your own words. Create an example of an extraneous solution for an equation. 8. Copy the definition of irreversible step in your own words. Create two examples for equations; one where the irreversible step creates an extraneous solution, and another one where the irreversible step causes you to lose a solution. Chapter 1.6 Inequalities 1. Copy the section objective 2. Define inequality and restate in your own words. Give two examples of inequality statements. Example 1: Graph the solution set of 2x+7>10 How would the graph be different if the inequality was 2x+7≥10? 3.Copy the multiplication property of order from page 28. Then write out the similar property for x>y. 4.Explain (in complete sentences in English) why you flip the inequality sign when you multiply or divide by a negative number, but you do not flip the inequality sign when you add or subtract a negative number. Example 2: Graph the solution set of – 3x≤12 Example 3: Graph the solution set of 4≤ 3x+1<9 Example 4: Graph the solution set of x 13 Example 5: Graph the solution set of x 13 5.
