Other possibilities is that f is an annihilator for ◦ operator, or that involved constituents are complex.

If we take multiplication for ◦, an annihilator value would be 0: 1*0 = 2*0, but 1 != 2. And with complex number arithmetic, even different g1/g2 when multiplied by same value f can result in equal values. Latter is best demonstrated by matrix representation and defining product as matrix multiplication: [[1, 1]] * [[1], [2]] = [[1, 1]] * [[2], [1]], but [[1], [2]] != [[2], [1]].

And both are applicable if you meant function composition, function equality holds only for real numbers and if neither of functions is defined as a constant.
