Graphing a quadratic equation examples
WebOn Example 1, the vertex was at (-5,4). Sal moved over 1 unit to pick x=-4. I believe he did this to demonstrate the impact of the -2 in front. It reduced the y-value of 4 by 2 units. … WebGraphing Quadratic Equations A quadratic equation is a polynomial equation of degree 2 . The standard form of a quadratic equation is 0 = a x 2 + b x + c where a , b and c are all real numbers and a ≠ 0 . In this equation, ( 0 , c ) is the y -intercept of the parabola.
