Let  X  be a continuous random variable with range  [0,1]  and its probability density function is given by:  f(x)=ax^2+bx+c where  a ,  b , and  c  are constants. Suppose that  E(X)=9/20 and  V(X)=31/400 . Find   a ,  b , and  c a= b= c= Find  P(0.7≤X≤1) Ans:

Expression, rule, or law that gives the relationship between an independent variable and dependent variable. Some important types of functions are injective function, surjective function, polynomial function, and inverse function.
