Scenario: Brenda's wedding is coming up in 11 months, and she wants to lose weight. She started at 160 pounds in November and hoped to be 30 pounds lighter by April. She started an exercise program and saw a nutritionist to help her with her diet. She started off well; however, after early success, she slacked off with exercise, started to eat unhealthy, and returned to her starting weight. Her fiancé helped her by telling her he would buy her a pearl necklace for the wedding if she lost 30 pounds. Use the graph provided to complete the graphical analysis.
