What is the domain of a quadratic function?

A quadratic functions, as all the polinomyal functions, don't have any restrictions.

The domain of a quadratic function is all real numbers, unless there are specific restrictions mentioned due to factors such as square roots or denominators.

The domain of a quadratic function is all real numbers unless restricted by a specific context or problem. In other words, the domain of a quadratic function ( f(x) = ax^2 + bx + c ) is ( (-\infty, +\infty) ), unless there are constraints such as division by zero or square root of a negative number, which would lead to undefined values.

The domain of a quadratic function is all real numbers unless restricted otherwise. In other words, any value of ( x ) is acceptable for a quadratic function unless it causes the function to be undefined, such as when dividing by zero or taking the square root of a negative number.
