E[X]=2(adsbygoogle = window.adsbygoogle || []).push({});

Var(X)=3

Find E[4+4x+x^2]

I'm just confused what its asking. The expected value of this function is 2 so the average of it is 2 and the variance is how much it varies which is 3? Every example I have for expected values is related to an example such as cards, not just a polynomial
