... expression that can be formed by: • If P is an n-ary predicate and each of the expressions x1, x2, … , xn is a term, then an expression of the form P(x1, x2, … , xn) is a wff. If any variable occurs in such a wff, then that variable occurs free in P(x1, x2, … , xn) . • If P is a wff, then P is a wf ...

... The right hand side of this equation is only valid where (7 − x)(x − 2) ≥ 0. So let’s find the range of x that satisfies this inequality first. Clearly, the equation (7 − x)(x − 2) = 0 at x = 7, 2. So we can divide the real line into three chunks: (−∞, 2), [2, 7], and (7, ∞). You can easily make a t ...
