13-2 Solving Quadratic Equations by Graphing – We practiced finding the roots or zeros of a quadratic equation by graphing. We learned that the x-intercepts are the zeros of the function. Then we learned that we can name the two roots by naming the two numbers that the root falls between. Next we saw an example where there were no roots because the parabola did not cross the x-axis. We completed two of the homework problems.
