اگر $f\left( x \right)=۲x+۵$ و $g\left( x \right)={{x}^{۲}}+۳$ باشند، $\underset{x\to ۲}{\mathop{\lim }}\,\left( f\left( x \right)+g\left( x \right) \right)$ کدام است؟
$\underset{x\to 2}{\mathop{\lim }}\,\left( f\left( x \right)+g\left( x \right) \right)=\underset{x\to 2}{\mathop{\lim }}\,f\left( x \right)+\underset{x\to 2}{\mathop{\lim }}\,g\left( x \right)=\underset{x\to 2}{\mathop{\lim }}\,\left( 2x+5 \right)+\underset{x\to 2}{\mathop{\lim }}\,\left( {{x}^{2}}+3 \right)=9+7=16$
