Suppose t : r r3 is an onto linear transformation. list all of the possible echelon forms of the standard matrix for t. use the notation of problem three above. 5. if a linear transformation t: ra+ rb is one-to-one, what must be true about a and b? i. e. can you give a relation between a and b? explain the reason for your answer using complete sentences. ro is onto, what must be true about a and b? ie. can you give a relation 6. if a linear transformation t: ra between a and b? explain the reason for your answer using complete sentences.
