But it can The difficulty of graphing a quadratic function varies depending on the form you find it in. This makes sense given that the vertex is at -1, -2 and the parabola points down, so the function won't go up towards the x -axis. So the maximum value for y is at 5. This is my x-axis. Plot a few more points, and use the function's symmetry to sms zdarma more points. This is a maximum point, it's a maximum point for this parabola. Example 4 — Graph: Some say the use of dynamite while hunting is unsportsmanlike. Example 3 — Graph: It's the same with this equation. Find the vertex of the following parabola: Example 3 — Graph: Intro Topics Imaginary and Complex Numbers Solving Quadratic Equations Completing the Square Quadratic Formula How Many Roots? It could be equal to 0. We'll start things off relatively easily. Guess we won't need that dynamite after all. We immediately see that the vertex is at -1, -2 , and the parabola opens down. So that's 1, the vertex, that's interesting.
