How to fill out quadratic equations and parabolas

How to fill out quadratic equations and parabolas:

1. Start by identifying the form of the quadratic equation. Quadratic equations can be written in standard form (ax^2 + bx + c = 0), vertex form (y = a(x - h)^2 + k), or intercept form (y = a(x - p)(x - q)).
2. If the quadratic equation is given in standard form, you can use the quadratic formula (x = (-b ± √(b^2 - 4ac))/(2a)) to find the solutions for x. The discriminant (b^2 - 4ac) will determine the nature of the solutions.
3. If the quadratic equation is given in vertex form, you can easily identify the vertex (h, k) and use that information to graph the parabola.
4. If the quadratic equation is given in intercept form, you can find the x-intercepts (p and q) and the y-intercept (c) to graph the parabola.
5. To graph a parabola, plot the coordinates of the vertex and use the axis of symmetry (x = h) to find other points on the parabola. Additionally, you can use the x-intercepts and y-intercept to further plot points.
6. You can also use the properties of the parabola to determine the direction of the opening (upward or downward) and the axis of symmetry.
