    Trying to study for my exam and would like to see how u would solve functions so plz

    1.Let A = {1; 2; 3; 4} and B = {a; b; c}. Give an example of a function f:A Bthat is neither one to one nor onto.
    2. Determine ifthe function f:- {0} defined as f(x) =1/x+ 1 is one to one and onto.

    3. Determine ifthe function f : ℝ- {2} - {5} defined by f(x) =5x + 1/x - 2is invertible. If it is define the inverse function f^-1.

    4. Determine ifthe function f:- {1} defined by f(x) =(x + 1/x 1)^3is one to one .

    5. Determine ifthe function f: defined as f(x) = 3 (-1)^x is one to one.

    6. Determine if the function f:{0, 1} defined as f(x) = 3 -1)^x is one to one.

    That is too many questions for one thread.
    You have simply listed the question.
    You have shown no effort whatsoever.

    This not a homework service nor is it a tutorial service.
