2. We define f: R→ R as a strictly increasing function if f(x) > f(y) whenever x > y, and x, y Є R. If f is a strictly increasing function as defined above, then it must be true that: a) f is injective (one-to-one) b) f is surjective (onto) c) f is bijective (one-to-one and onto) d) none of the above
