For any positive integer n, the function f n (x) = c n x (n-2)/2 e -x/2

Question:

For any positive integer n, the function fn(x) = cn x(n-2)/2e-x/2, x ≥ 0, where cn is an appropriate constant, is called the chi-square density function with n degrees of freedom. Find c2 and c4 such that f2 (x) and f4 (x) are probability density functions.
