Question

Let f:Z?Z be a function defined by f(x)=2x+3. (a) Is f one-to-one (injective)? If it is prove it, if it is not give a specific counterexample. (b) Is f onto (surjective)? If it is prove it, if it is not give a specific counterexample. (c) Is the function f a bijection? Explain why or why not.

Let f: Z -> Z be a function defined by f(x) = 2x + 3. (a) Is f one-to-one (injective)? If it is, prove it. If it is not, give a specific counterexample. (b) Is f onto (surjective)? If it is, prove it. If it is not, give a specific counterexample. (c) Is the function f a bijection? Explain why or why not.
