Important Notes on Standard Form of Quadratic Equation:A quadratic equation in standard form is ax2 + bx + c = 0. A quadratic equation in vertex form is a (x - h)2 + k = 0, where h = -b/2a and k = (4ac - b2) / (4a). A quadratic equation in intercept form is a (x ...
equationy = x + 3isy = 3, the y intercept of the equationy = x –2isy = -2, and the y intercept of the quadratic function isy = -6. There is a relationship between them. In fact, the y intercept of the parabola is the product of the y intercepts of the linear equations! In...
