Question

F(x)=0 if x if lesser or equal to 0
F(x)=x^2/4 if 0 is lesser than x which is lesser or equal to 2
F(x)=1 if x is greater than 2

I already did a question for this one so sorry if you are seeing this again, but I wrote the original one incorrectly and still was unable to get help in finding out how to graph the above as a density function and a distribution function. Any help would be appreciated! Thanks!
