If `P(x) = a _0 + a _1 x ^(2) + a _2 x^(4) + … + a _n x ^(2n)` is a polynomial in a real variable `x` with `0 lt a _0 lt a _1 lt a _2 lt … lt a_n`. Then, the function `P (x)` has

Let P(x) = a_(0) + a_(1)x^(2) + a_(2)x^(4) + ..........+ a_(n) x^(2n) be a polynomial in a real variable x with 0 lt a_(0) lt a_(1) lt a_(2) lt ……………. lt a_(n) The function P(x) has :

Let P(x) = a_(0) + a_(1)x^(2) + a_(2)x^(4)+...+a_(n)x^(2n) be a polynomial in a real variable x with 0 lt a_(0) lt a_(1) lt a_(2) lt ... lt a_(n) . The function P(x) has

Let P(x)=a_(0)+a_(1)x^(2)+a_(2)x^(4)+a_(3)x^(6)+……+a_(n)x^(2n) be a polynomial in a real variable x with 0 lt a_(0) lt a_(1) lt a_(2) lt ……… lt a_(n . The function P(x) has :

p(x)=a_(0)+a_(1)x^(2)+a_(2)x^(4)+…………+a_(n)x^(2n) is a polynomial with real variable x. If 0 lt a_(0)lt a_(1)lt a_(2)lt ……….lt a_(n) then p(x) has …………

If a random variable X has the p.d.f. f(x)=k/(x^(2)+1), 0 lt x lt infty , then k is
