can someone explain why I got it wrong please

4 0 / 6 points Let f(x) = xfor 0

O/ 6 points Let f(x) = xfor O < x 1. Is f(x) a legitimate probability distribution function (pdf) for a continuous random variable? Yes, all criteria for a pdf are satisfied. C] No, the area underf(x) is not 1 (it is greater than 1). C] No, the area under f(x) is not 1 (it is less than 1). No, f(x) is not non-negative.
