Homework Statement
Find a basis of the image im(LA) of the linear transformation
LA: R^5 [tex]\rightarrow[/tex]R^3, x[tex]\mapsto[/tex]Ax
where
A =
1 -2 2 3 -1
-3 6 -1 1 -7
2 -4 5 8 -4
and hence determine the dimension of im(LA)
The Attempt at a Solution
Using the equation LA= Ax,
can i set up an augmented matrix of A and say, y1, y2 and y3 on the end? Then perform row reduction to get it into row reduced echelon form. Is that the right way to go about it? I will perform the calculation and update with it but any direction would be greatly appreciated.
