Problem B2
Find all functions f defined on the non-negative reals and taking non-negative real values such that: f(2) = 0, f(x) ≠ 0 for 0 ≤ x < 2, and f(xf(y)) f(y) = f(x + y) for all x, y.
Solution
f(x+2) = f(xf(2)) f(2) = 0. So f(x) = 0 for all x ≥ 2.
f(y) f((2-y)f(y)) = f(2) = 0. So if y < 2, then ... | HuggingFaceTB/finemath | |
