Thus, we can say that the function $f$ is one-way function. We have language $L = \ { w \; \; \exists z \in \Sigma^*, w = f (z)\}$.
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 ( … WebTo be Injective, a Horizontal Line should never intersect the curve at 2 or more points.
