# S2 help!! watch

1. Hey guys, any chance of some S2 help? When drawing a probability density function for X as below, as 1 is not equal to x but to 3x^2/14, you draw it as 3/14 and not as 1 right?

If that's the case, why is 1 the mode??

these are "pure technicalities" together with "statistical greyness"
think of the PDF as a scaled histogram
you can get to the maximum height of 1 (or as close as possible to 1) when x =1
then you fall down a big cliff onto a quadratic.
I definitely think the mode is 1 but I do not know if I convinced you ..
at the other end (x=2) you are not as high
