If f(x) is odd and f(-3)=5, what is f(3)?

If f(x) is an odd function and f(-3)=5, what is f(3)?

Please show me how you do this type of problem if you can. :)

Update:

Um well this is literally the problem on my homework. The function f(x) is an *odd function* Hopefully that makes more sense.

    If f(x) is an odd function, and when the input is negative and comes out positive, then I think that what it is getting at is that when the input is positive, the output will be negative.

    Odd functions, when graphed, have ends going in generally opposite directions/quadrants (unlike a parabola). If this is truly the COMPLETE homework question, it may have to be assumed that the answer is -5, also assuming that the function is very basic without any strange transformations.

    'ƒ(x) is odd' means,

    ƒ(x)=-ƒ(-x)

    !!!... how is your ƒ(x) related to ƒ(-3)?...

    If i assume The question means,

    If ƒ(-3) =5 is odd,find ƒ(3).

    Then,

    ƒ(-3) =5

    ƒ(-3) = -ƒ(3)

    ƒ(3) = -ƒ(-3)

    ƒ(3)= -5

    So,ƒ(3) would be -5
