comment $\det (A^2 - I) < 0 \Rightarrow \lambda \in (-1,1)$
@PraphullaKoushik why $f(x)$ is continuous?

comment Let $f:[-1,1] \to \mathbb{R}$ be differentiable 3 times, prove $\exists M>0 \ , \ s.t \ f(x) \le Mx^2$
Why $f'(0)=0$? Can you explain?

accepted $x_1,x_2,x_3,x_4$ are in Harmonic Progression $\Rightarrow (x_1-x_3)(x_2-x_4)=4(x_1-x_2)(x_3-x_4)$

comment Number of Fixed Point(s) of a Differentiable Function
MVT on $[x,x']$ allows me ${f(x)-f(x')\over x-x'}=f'(c)<1$, $c\in [x,x']$
