Question

Yes or No? If No, give a reason. Let f be a function.

(a) Is it possible that f(6) = 3

 and f(7) = 3?

Yes.No. A function assigns each value of x in its domain to exactly one value of f(x).    No. A function assigns each value of f(x) in its range to exactly one value of x.No. A function expecting a variable cannot be called with a constant argument.No. There is no possible function operations that would yield 3 from 7.

(b) Is it possible that f(6) = 3

 and f(6) = 8?

Yes.No. A function assigns each value of x in its domain to exactly one value of f(x).    No. A function assigns each value of f(x) in its range to exactly one value of x.No. A function expecting a variable cannot be called with a constant argument.No. There is no possible function operations that would yield 8 from 6.
