Given that FX is an even function of period 2 and an increasing function in the interval [0,1], then f (- 5.5), f (- 1) and f (0) are of the same magnitude

Given that FX is an even function of period 2 and an increasing function in the interval [0,1], then f (- 5.5), f (- 1) and f (0) are of the same magnitude

∵ f (- 5.5) = f (- 3 × 2 + 0.5) = f (0.5) f (- 1) = f (- 1 × 2 + 1) = f (1), and f (0) < f (0.5) < f (1) ∵ f (0) < f (- 5.5) < f (- 1)
