Check if function is bijective

WebIt is bijective. The best way to show this is to show that it is both injective and surjective. Injective means one-to-one, and that means two different values in the domain map to two different values is the codomain. You can see that 3x - 2 is linear, so clearly two different x values will give two different y values. WebAlternatively, f is bijective if it is a one-to-one correspondence between those sets, in other words both injective and surjective. Example: The function f(x) = x2 from the set of …
