How to show injective

WebTo test injectivity, one simply needs to see if the dimension of the kernel is 0. If it is nonzero, then the zero vector and at least one nonzero vector have outputs equal 0 W, implying that the linear transformation is not injective. Conversely, assume that ker ( T) has dimension 0 and take any x, y ∈ V such that T ( x) = T ( y). Webf: N → N. defined by f ( x) = 2 x for all x in N is one to one. Is my proof correct and if not what errors are there. For all x 1, x 2 ∈ N, if f ( x 1) = f ( x 2), then x 1 = x 2. f ( x) = 2 x. Assume f ( …
