A quadratic function is a function where a variable is raised to the second degree (2). Examples would be x2, or for more complexity, 2x2+4x+16. The quadratic formula is a way of finding the roots of a quadratic function, or where the parabola crosses the x-axis. There are many ways of finding roots, but the quadratic formula will always work for any quadratic function. In the form ax2+bx+c, the Quadratic Formula looks like this: x=-b±√b2-4ac _________ 2a The plus-minus means that there can 2 solutions.
If the quadratic function is f(x) = ax^2 + bx + c then its inverse isf'(x) = [-b + +/- sqrt{b^2 - 4*(c - x)}]/(2a)
Yes. A quadratic function can have 0, 1, or 2 x-intercepts, and 0, 1, or 2 y-intercepts.
A polynomial of degree 2.
A quadratic function is a function that can be expressed in the form f(x) = ax^2 + bx + c, where a, b, and c are constants and a is not equal to 0. This function represents a parabolic shape when graphed.
(x - 4)(x + 3) foil y = x^2 - x - 12 ----------------------
A quadratic function will have a degree of two.
The expression (2X^2 - 7X - 4) is a quadratic polynomial in the variable (X). It represents a parabolic function when graphed, with a leading coefficient of 2 indicating that the parabola opens upwards. The roots of this polynomial can be found using the quadratic formula, and it can also be factored if possible.
It follows from the definition of a quadratic funtcion.
A quadratic function is a second degree polynomial, that is, is involves something raised to the power of 2, also know as squaring. Quadratus is Latin for square. Hence Quadratic.
That the function is a quadratic expression.
A linear function is a line where a quadratic function is a curve. In general, y=mx+b is linear and y=ax^2+bx+c is quadratic.
Lemniscate
f(x) = ax^2 + bx + c, where a != 0 (for obvious reason: it wouldn't be a quadratic function)

The equation for a circle is a function in that it can be graphed and charted. One common equation is x^2 + y^2 = r^2.
