Decide whether the function f(x) = = 12 2_ 3 10 is a probability density function on [ - 1, 1]. If not, tell why. Is the function a probability density function on [ - 1, 1]? O A. No, because f(x) is not greater than or equal to 0 for all x in [ - 1, 1]. O B. Yes, the function is a probability density function on [ - 1, 1]. O C. No, because dx # 1 . - 1
