Suppose f(x)= 0.25.What range of possible values can X take on and still have the density function be legitimate?
A)[0,4]
B)[4,8]
C)[−2,+2]
D)All of these choices are true.

Since f(x) = 0.25 is a constant for all values of x, the function is flat and has a constant area underneath it. That means there is no restriction on the range of possible values for x, and thus all the choices are true.

Suppose F(x)= 0
