Hi I'm Heather and I'm doing my Masters in Statistics.

I have a calculus prob.

I have this question about pdf:

Suppose X be a continuous random variable with the pdf:

f(x) = {k (2 +x^2 -x) -1 <= x <= 2

0 otherwise

I need to find the value of k, which is a positive constant and then obtain the cumulative distribution function (F (x)) of X.

Can someone help please?
