A function that can be represented by an equation of the form y = ax2 (or ax^2) + bx + c, where a, b, and c are arbitrary, but fixed, numbers and a 0. The graph of this function is a parabola.

A polynomial function of degree two of the form

A function of the second degree [i.e., a function of the form f(x) = ax2 + bx + c]; in a rectangular coordinate system, the graph of a quadratic function is a parabola.

an equation in the form y = ax2 + bx + c where a is not equal to zero radicand - number under the radical sign

A function that has an equation of the form y = ax2 + bx + c, wherea ยน 0. These functions can be used to describe the flight of a ball, acceleration/deceleration problems, and the stream of water from a fountain.

A function of the form f(x) = ax2 + bx + c where a is not equal to zero (in which case the function turns into a linear function)

A function given by a polynomial of degree 2. The graph of these functions are parabolas. The equations can be represented in the form of y = ax2 + bx + c where a,b, and c and fixed numbers and a zero.

A quadratic function, in mathematics, is a polynomial function of the form f(x)=ax^2+bx+c \,\!, where a, b, c \,\! are real numbers and a \ne 0 \,\!. It takes its name from the Latin quadratus for square, because quadratic functions arise in the calculation of areas of squares. Because the (highest) exponent of x is 2, a quadratic function is sometimes referred as a degree 2 polynomial or a 2nd degree polynomial.
