Hi,

I am stack with this question, could you place help me I don't know from where to start

Thanks,

For the given vector spaces ! and the given subsets of V , either prove that they are subspaces , or explain why they are noes. orwhy they( 2 )VERW = ( ( W X 3 2 ) ER 4 : W + 3x - 5 + 3 = 0 )M2 x 2 ( 18 )10 - * + 2yHE VERV = F ( R )W = ( ( x ) f ( x ) 2 0 for all x )
