WebFeb 5, 2024 · Critical points exist where the derivative is 0, and represent points at which the graph of the function changes direction from decreasing to increasing, vice versa. … WebSep 11, 2024 · The critical points are simply those points on the x-axis where f(x) = 0. The Jacobian matrix is [ 0 1 − f ′ (x) 0]. So the critical point is almost linear if f ′ (x) ≠ 0 at the critical point. Let J denote the Jacobian matrix, then the eigenvalues of J are solutions to 0 = det (J − λI) = λ2 + f ′ (x). Therefore λ = ± √− f ′ (x).
