Many graphs have a line of symmetry that runs through the center of the graph, creating two perfectly identical halves. The formula to find the line of symmetry of a quadratic function is x=-b/2a, where a and b are determined from the standard form ax^2 + bx + c = 0.Understanding...
The parabola represents the graph of a quadratic function. The axis of symmetry is the value where the graph is divided into two equal parts. We can obtain the axis of symmetry of a quadratic function by finding the x-coordinate of the vertex, which uses the following fo...
A quadratic function has a degree equal to two. So this polynomial function is described by a curve. The curve that describes the behavior of a quadratic function has a single critical point and is called the vertex. A vertical line known as the axis of symmetry passes through this p...
