WebHence it looks like f ( x) = x 2 − 2 is a good candidate. Of course, x + 1 x ≥ 2 implies that we cannot say anything about f ( x) if x < 2 . But for x ≥ 2, we can find a real number t such that t 2 − x t + 1 = 0 (and hence t + 1 t = x ), namely t = x ± x 2 − 4 2, and then see that indeed f ( x) = f ( t + 1 t) = t 2 + 1 t 2 = x 2 − 2. WebSep 18, 2024 · On the graph of a line, the slope is a constant. The tangent line is just the line itself. So f' would just be a horizontal line. For instance, if f(x) = 5x + 1, then the slope is just 5 everywhere, so f'(x) = 5. Then f''(x) is the slope of a horizontal line--which is 0. So …
