In Exercises 25–28, determine if the specified linear transformation is (a) one-to-one and (b) onto. Justify each answer.The transformation in Exercise 2Exercises 2: Assume that T is a linear transformation. Find the standard matrix of T. where e1, e2, and e3 are the columns of the 3 × 3 identity matrix.

SOLUTIONStep 1 Assume that T is a linear transformation. Find the standard matrix of T. where e1, e2, and e3 are the columns of the 3 × 3 identity matrix.We need to show whether the the transformation is one-one or onto.
