For the squaring function $f(x)=x^2$ defined on all real numbers, the domain is the set of all real numbers ($\mathbb{R}$), meaning every input is allowed. The range is the set of all nonnegative real numbers ($[0, \infty)$), because squaring any real number results in a value greater than or equal to zero.

Conditions: The function is $f(x)=x^2$.; The domain is specified as all real inputs.
