Show that the relation R defined on the set A of all polygons as R = {(P₁ P₂) : P₁ and P₂ have same number of sides} is an equivalence relation.

Let f and g be real functions defined by \(f(x)=\sqrt{x+2}\)and \(g(x)=\sqrt{4-x^2}\). Find f + g

For the curve \(y={ -x }^{ \left( \frac { 1 }{ 3 } \right) }\) given in figure, draw.

Let A = {2, 3, 5} and relation R = {(2, 5)} write down the minimum number of ordered pairs to be included to R to make it an equivalence relation.
