Tamara and Alex arrive at a park at the same time. Tamara lives 8 mi from the park and Alex lives 6 mi from the park. After meeting at the park, Tamara goes to a store that is 8 mi from the park, while Alex goes to a store that is 6 mi from the park. The function f(x) = 2|x| represents Tamara’s time and distance from her home to the park and then to the store. The function g(x) = 3|x| represents Alex’s time and distance from his home to the park and then to the store. Graph each absolute value function. Identify the vertex of each graph. What does the vertex represent?
