Given the parabola x 2 − 2 x − 2 y + 3 = 0, find the vertex, focus, directrix and axis of symmetry. Axis of Symmetry and Vertex of a Parabola For a parabola with equation y = ax2 +bx + c y = a x 2 + b x + c: The axis of symmetry of a parabola is the line x = − b 2a x = − b 2 a. The sliders h and v move the curve either horizontally (left or right), or vertically (up or down). Where, h and k can be found using the formula, h = -b / 2a k = 4ac - b 2 / 4a The Focus of the Parabola: The focus is the point that lies on the axis of the symmetry on the parabola at, F(h, k + p), with p = 1/4a. If the axis of symmetry is horizontal, then the parabola is horizontal. So the first would be (5,-23). The axis of symmetry always passes through the vertex of the parabola. Well one way would be to find the average value of the X or that is: simply add the two values where the symmetry is (in parabola case, the x axis), so how do you find the average? Where, h and k can be found using the formula, h = -b / 2a k = 4ac - b 2 / 4a The Focus of the Parabola: The focus is the point that lies on the axis of the symmetry on the parabola at, F(h, k + p), with p = 1/4a. Note that the horizontal distance from this point to the right side of the curve (with respect to the axis of symmetry) is always equal to the corresponding point on the left side of the curve. The x-intercept is -2 and -4, the y intercept is 8, the domain is R, the range is [-1, inf.] Since the axis of symmetry lies on the x-axis, we take the y-intercept.
