Web$\begingroup$ @Dilip When a definition depends on one way of describing something, but that definition can be shown to be an intrinsic property of that something, then it makes no sense to apply the definition to a different form of description. In this case, symmetry is a property of a distribution, but that does not imply that all descriptions of that distribution … WebWhich of the following is a symmetric function of the roots of a quadratic function with roots x 1 and x 2? 1.

WebA function in α and β is said to be a symmetric function if the function remains the same when α and β are interchanged. Consider α +β. When α is written as β, and β is written as α, the function becomes β + α, which is same as α+β. So α +β is a symmetric function of the roots. αβ is also a symmetric function of the roots as ...
