When y = 3, which of the following is FALSE?
A. y is prime and y is odd

B. y is odd or y is even

C. y is not prime and y is odd

D. y is odd and 2y is even

  • math -

    I'am not sure about this

  • math -

    well, 3 is an odd number and it is prime
    and 2y or 6 is clearly even.

    So which choices do you think are false ?

    If f and g are functions defined for all real numbers, and f is an odd function, then f ∘ g is also an odd function. Justify. I wrote false cause for example if f = x^3(odd) and g=x^2(even) the fog is even.
