- NOTE: if the parabola opened left or right it would not be a function! y x Vertex Vertex y = ax2 + bx + c The parabola will open down when the a value is negative. The parabola will open up when the a value is positive. y x The standard form of a quadratic function is a > 0 a < 0 y x Line of Symmetry Parabolas have a symmetric property to them.
- Equation 1. The y-intercept is at the point (0,24). The graph has a minimum, because the coefficient of x is positive. Equation 2. The graph has a minimum and has roots at (4,0) and (6,0). Equation 3. The graph has a minimum turning point at (5, −1). If students struggle to write anything about Equation 3, ask:
- Quadratic equations are mathematical functions where one of the x variables is squared, or taken to the second power like this: x 2. When these functions are graphed, they create a parabola which looks like a curved "U" shape on the graph. This is why a quadratic equation is sometimes called a parabola equation.
- A quadratic equation is an equation where the largest power for the variable is 2. Remember that an equation has an equal sign in it. Some examples of quadratic equations are: Quadratic equations can be solved in order to find the roots of the equation. Roots are also called zeros or x–intercepts if the graph crosses the x–axis.

- Earlier, we saw that quadratic equations have 2, 1, or 0 solutions. The graphs below show examples of parabolas for these three cases. Since the solutions of the equations give the x-intercepts of the graphs, the number of x-intercepts is the same as the number of solutions. Previously, we used the discriminant to determine the number of ...
- g(x) = -0.2x 2 - 0.4x + 2.8 Of course, quadratic functions, or second degree polynomial functions, graph as parabolas. Since we will be graphing these functions on the x, y coordinate axes, we can express the parabolas this way:
- The domain of a rational function is restricted where the denominator is 0. In this case, x + 2 is the denominator, and this is 0 only when x = −2. For the range, create a graph using a graphing utility and look for asymptotes: One asymptote, a vertical asymptote, is at x =−2, as you should expect from the domain restriction.
- Graph the following and identify the vertex, axis of symmetry, domain & range Use the equation to answer the following questions: b Max or Min 2. +17 Vertex: Domain: Axis of Symmetry: Range: 3.

- graphs of quadratic equations. First and foremost, the graph of y= ax2 + bx+ cwhere a, b, and care real numbers with a6= 0 is called a parabola. If the coe cient of x2, a, is positive, the parabola opens upwards; if ais negative, it opens downwards, as illustrated below.1 vertex a>0 vertex a<0 Graphs of y= ax2 + bx+ c.
- Parabola Equation Solver based on Vertex and Focus Formula: For: vertex: (h, k) focus: (x1, y1) • The Parobola Equation in Vertex Form is:
- The function above on the left, y = x 2, has leading coefficient a = 1≥ 0, so the parabola opens upward. The other function above, on the right, has leading coefficient -1, so the parabola opens downward. The standard form of a quadratic function is a little different from the general form. The standard form makes it easier to graph. Standard ...
