![]() ![]() This possibly will be ascribed to several reasons. There is a somewhat or to some extent a misconception of the duties of some of the experts in the running and administration of Construction projects (1). the equation of the axis of symmetry is x =-b/2a. Key Concept-Graph of a Quadratic Function. The x-intercepts are the points at which the parabola crosses the x-axis. The y-intercept is the point at which the parabola crosses the y-axis. The graph is also symmetric with a vertical line drawn through the vertex, called the axis of symmetry. In either case, the vertex is a turning point on the graph. The axis of symmetry will have the equation x = h. A parabola with its vertex at (h, k), opening vertically, will have the following properties. The zeroes, also known as the roots, are the x-intercepts of the parabola. We will be taking a look at these four features in this presentation. Nonetheless, there are many key features in a quadratic graph such as the zeroes (x-intercepts, also known as the roots), y-intercept, axis of symmetry, and the vertex. The graph of a quadratic function is a parabola which opens up if a > 0 and opens down if a < 0. A quadratic function is a function whose rule may be written in the form f(x) = ax 2 + bx + c where a, b, and c are real numbers and a is not zero. ![]()
