Lastly, we looked at how we could solve quadratics by using a graphing method. We used desmos.com and graphed the left side of the equation in the first entry line (can use f(x) or y = if you want) and the right side of the equation was the second entry line. We say that if we entered just a number, we had to use y = or function notation. Then we just clicked on the intersection points and wrote down the x-coordinate. We complete 16 & 17 together (on WS 4-5).
