How Do You Graph A Quadratic Formula A Quadratic Equation a b and c can have any value except that a can t be 0 Try changing a b and c to see what the graph looks like Also see the quot roots quot the solutions to the equation Then read more about the Quadratic Equation
A quadratic equation is drawn as a curve on a set of axes This type of curve is called a parabola and it is symmetrical To draw the graph we need coordinates y a x h 2 k is the vertex form equation Now expand the square and simplify You should get y a x 2 2hx h 2 k Multiply by the coefficient of a and get y ax 2 2ahx ah 2 k This is standard form of a quadratic equation with the normal a b and c in ax 2 bx c equaling a 2ah and ah 2 k respectively 1 comment
