Hello everyone, i'm confused on this problem:(adsbygoogle = window.adsbygoogle || []).push({});

It says:

A linear transformation T:R^3->R^2 whose matrix is

2 -4 -3

-3 6 0+k

is onto if k != ?

!= meaning, not equal.

So my thinking was, For it to be a transformation into R^2, doesn't that mean k isn't suppose mean that the column

-3

0+k

has to some how come out to be

0

0

so your only left with

2 -4

-3 6

so that would be in R^2 right?

i'm confused, am i thinking wrong? or is there some trick to easily find what k isn't suppose to be? Thanks!
