f\left( x \right) = \left\{ {\begin{array}{cccccccccccccccccccc} {x,x < 0}\\ {1,x = 0}\\ {{x^2},x > 0} \end{array}} \right.

, then

\lim\limits_{x \to 0} f\left( x \right)

View answer and explanation

Correct option: A

Option A (0) is correct because both the left-hand limit and the right-hand limit of f(x) as x approaches 0 are equal to 0.

\lim \limits_{{x \rightarrow 0}}\left(\frac{1}{x^2}-\operatorname{cosec}^2 x\right)

\lim _{x \rightarrow \frac{\pi}{2}} \frac{\cos x}{(1-\sin x)^{2 / 3}}=

\lim\limits_{h \to 0} 2\left\{ {\frac{{\sqrt 3 \sin \left( {\frac{\pi }{6} + h} \right) - \cos \left( {\frac{\pi }{6} + h} \right)}}{{\sqrt 3 h\left( {\sqrt 3 \cos \,h - \sin \,h} \right)}}} \right\}

\lim \limits_{{x \rightarrow \infty}} x\left(e^{1 / x}-1\right)

f(x)=\frac{(x+1)^7 \sqrt{1+x^2}}{\left(x^2-x+1\right)^6}
