Let p be the vector space (over r) of all polynomials of degree 3 with real consider the linear coefficients. transformation t:p-p defined by t(a +a,x+a,x +a,x)

Let P be the vector space (over R) of all polynomials of degree 3 with real Consider the linear coefficients. transformation T:P-P defined by T(a +a,x+a,x +a,x)= a, +a,x +a,x +ax. Then the matrix representation of Mof T with respect to the ordered basis 1, x, x2, x3 satisfies.
