Wavy Curve Method | Brilliant Math & Science Wiki

The wavy curve method (also called the method of intervals) is a strategy used to solve inequalities of the form (frac{f(x)}{g(x)} > 0) (left(<0,, geq 0,, text{or}, leq 0right).) The method uses the fact that (frac{f(x)}{g(x)}) can only change sign at its zeroes and vertical asymptotes, so we can use the roots of (f(x)) and (g(x)) to sketch a graph of the …
