I have hard to understand this input for this linear map \(\displaystyle T_3(R)->P_2(R)\)

\(\displaystyle T(p(x))=P'(1-x)\)

so they get this value when they put in which I have hard understanding

I dont understand how they get those, I am totally missing something basic...!!

The only logical explain is that in \(\displaystyle p'(x)=3x^2\) where \(\displaystyle x=(1-x)\) I dont get it.
