We completed a Chapter 9 review of ordered pairs, domain, range, and inverses of relations for extra credit on the test. We also labeled quadrants, axes, and the origin. Then we worked on identifying whether relations are functions by examining solution sets, mappings, and graphs. Next we determined whether equations were linear by graphing the coordinates from a table. We practiced solving equations for y in order to create a table of ordered pairs for a graph. We also discovered which equations have graphs that are vertical lines. Next we were able to evaluate quadratic equations for functions with respect to x. We practiced finding roots of a quadratic equation by identifying where the parabola crosses the x-axis by identifying the two points on either side of the point. We used the formula for calculating the axis of symmetry of a quadratic equation.
