Parabola in fig. 1 opens
WebThe graph of a quadratic function is a U-shaped curve called a parabola. One important feature of the graph is that it has an extreme point, called the vertex. If the parabola opens up, the vertex represents the lowest point on the graph, or the minimum value of the quadratic function. WebHow to find Maximum & Minimum of a parabola on a graphing calculator: 1. Go to y= button 2. Type in the problem equation. 3. Hit graph button. 4. Move cursor to the left of the parabola.

When a parabola opens up or down, its equation in the standard form is of the form y = ax 2 + bx + c. Here are the steps to find the vertex (h, k) of such parabolas. The steps are explained with an example where we will find the vertex of the parabola y = 2x 2 - 4x + 1.
