WebJan 16, 2024 · Recognizing Characteristics of Parabolas. The 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. If the parabola … WebA parabola is the locus of a point that is equidistant from a fixed point called the focus (F), and the fixed-line is called the Directrix (x + a = 0). Let us consider a point P(x, y) on the parabola, and using the formula PF = …
