On this week, we finished lesson 5 and we practice lesson 5 for test on Thursday. After test on Thursday, we learned new lesson 8. This lesson is about solving absolute value equations.  An absolute value function has the form y = |f(x)|, where f(x) is a function. The x-intercept of the graph y = |f(x)| is a critical point. the graph of y = |f(x)| changes direction at this point. We can solve absolute value equations by graphing using the strategies.
