What I learned this week.

This week we reviewed real numbers, inequalities, absolute values, and equations of circles. In addition to inequalities, we learned how to write set notations, and how to use sign chart method to solve inequality equations with x^2. We learned how to solve inequalities with absolute values. We also reviwed the distance formula and midpoint formula. We reviewed intercepts and we learned the formula for semicircles. We reviewed how to rewrite the equation of circle if it is not written in the standard format. We also reviwed how to graph a circle.
