A quadratic function is a polynomial function of the form f(x)=ax^2+bx+c, where a cannot equal 0. It is a second degree polynomial with the highest exponent being 2. Setting a quadratic function equal to 0 produces a quadratic equation, whose solutions are the roots of the equation. Quadratic functions are commonly used to model real world phenomena like projectile motion or profit functions and appear in nature as parabolic shapes.
2. Definition Of Quadratic Function
A quadratic function, in mathematics, is a
polynomial function of the form
f(x)=ax2+bx+c
3. Definition Of Quadratic Function
The expression in the definition of a quadratic
function is a polynomial of degree 2 or second
order, or a 2nd degree polynomial, because the
highest exponent of x is 2.
If the quadratic function is set equal to
zero, then the result is a quadratic equation. The
solutions to the equation are called the roots of
the equation.
