F(x)>_0. All real numbers is an exaggeration

f(0) = 60(0) = 0 \\ f(1) = 60(1) = 60 \\ f(2) = 60(2) = 120 \\ f(3) = 60(3) = 180 \\ f(3.5) = 60(3.5) = 210

So we conclude that f(x) does not necessarily equal multiples of 60 only and f(x) cannot be negative hence all real numbers is an exaggeration, Finally


f(x) \geqslant 0
