How do you describe the graph of the quadratic function?
The graph of a quadratic function is called a parabola and has a curved shape. One of the main points of a parabola is its vertex. It is the highest or the lowest point on its graph. You can think of like an endpoint of a parabola.
What does a quadratic equation tell you about a graph?
When graphed, quadratic equations of the form ax2 + bx + c or a(x – h)2 + k give a smooth U-shaped or a reverse U-shaped curve called a parabola. Graphing a quadratic equation is a matter of finding its vertex, direction, and, often, its x and y intercepts.

What are quadratic functions & parabolas?
Quadratic Functions & Parabola Quadratic functions are all of the form: f(x) = ax2 + bx + c where a, b and c are known as the quadratic’s coefficients and are all real numbers, with a ≠ 0.
What is the graph of a quadratic function?
The graphs of quadratic functions are parabolas, but the general quadratic equation is Ax^2 + Bxy + Cy^2 + Dx + Ey + F = 0, and can represent any of the conics, a circle, eliipse, parabola, or hyperbola.
What is the formula for a parabola?
The Parabola. Given a quadratic function f(x) = ax2 + bx + c, it is described by its curve: y = ax2 + bx + c This type of curve is known as a parabola. A typical parabola is shown here: Parabola, with equation y = x2 − 4x + 5.
What is concave-down parabola?
Concave-Down Parabola, “unhappy parabola”. Given a parabola y = a x 2 + b x + c, the point at which it cuts the y -axis is known as the y -intercept . where c is the only term in the parabola ‘s equation without an x .
