range space and null space

Let,

determine a basis for the (a) range space of and (b) null space of

This is a subject of Linear Algebra.

ok. so how can i move it to there?

You can't. Perhaps one of the moderators will do it.

In any case, you are expected to show what you have tried. What is the definition of "range" and "null space" of a matrix?

Null space of the matrix is the collection of s where

and range of is the collection of all possible linear combinations of the column vectors of
