Q.39 If A=011101110, find A-1 and show that A-1=1/2A2-3I.

Q.39 If $A = [\begin{matrix} 0 & 1 & 1 \\ 1 & 0 & 1 \\ 1 & 1 & 0 \end{matrix}]$ , find $A^{- 1}$ and show that $A^{- 1} = 1 / 2 (A^{2} - 3 I)$ .

$f (x) = \{\begin{matrix} \frac{\sin (a + 1) x + \sin x}{x}, f o r x < 0 \\ x, f o r x = 0 \\ \frac{\sqrt{x + b x^{2}} - \sqrt{x}}{b x^{\frac{3}{2}}}, f o r x > 0 \end{matrix}$
