Let ≤ be a partial order over a set X and let f: X → X be a function over X. Then a prefixed point (also spelled pre-fixed point, sometimes shortened to prefixpoint or pre-fixpoint) of f is any p such that f(p) ≤ p. Analogously, a postfixed point of f is any p such that p ≤ f(p). The opposite usage occasionally appears. Malkis justifies the definition presented here as follows: "since f is before … how to strength train without weights

Setting the right-hand side equal to zero and factoring, we have − x(2 + 3y) = 0 y(3 − y) = 0 From the second equation, we see that either y = 0 or y = 3. The first equation then gives x = 0 in either case. So, there are two fixed points: (0, 0) and (0, 3).
