Thread: sketching help!!!

how do i sketch a probability density function.i cant find how to do it anywhere!driving me nuts

kx.........0

0 ........elsewhere

k=1 from my workings.thanks in advance

Draw the line y=x between 0 and 1 on the x-axis and the line y=2-x between 1 and 2 on the x-axis. It should be a triangle with an area of 1.
