To understand this, let us consider ‘f’ is a function whose domain is set A. The function is said to be one to one if for all x and y in A, x=y if whenever f (x)=f (y) In the same manner if x ≠ y, then f (x ...

Tis one-to-one if and only if the columns of Aare linearly independent; 2. Tis onto if and only if the columns of Aspan Rm. Remark. Given Theorem 3, we can perform row reduction on the standard matrix Ato determine whether the corresponding linear transformation Tis one-to-one or onto. We
WebIs f onto R? Is it one-to-one? If both, find its inverse. [As always, justify your answers!] Solution. By Theorem 3.24 [on pg. 36 from the textbook], we see that it suffices to show that f is invertible to show that it is also one-to-one and onto.
