## POlynomials use in parabolas

The "x" and "y" values of a polynomial make a point on a graph. In the "x^2" polynomial, you find the y-value by squaring the chosen x-value. For example, if the chosen x-value is "2," then the y-value is 2^2 = 2*2 = 4. When you draw all "x" and "y" values of the x^2 polynomial on a graph, you get a "U-shaped" image called a parabola. Parabolas show up in many of the devices around us, including parabolic microphones, satellite dishes and car headlights.
