2. Linear Maps(a) Let Pn denote the space of polynomial of degree at most n withreal coefficients. Find the matrix representation of the differentialoperator D : P3 → P2 given byD(at³ + bt² + ct + d) = 3at² + 2bt + c with respect to thestandard monomial basis for P3 and P2.(b) Do the same as above with {2, (t + 1)/2, t²} for a basis of therange of D (still use the standard monomial basis for the domain ofD ).

We have to find the matrix representative of differential operators using standard monomial basis.
