94. Find $\lim _{x \rightarrow 2}\left(3 x^{2}-2 x\right)$.
Solution. Using properties 1, 3, and 5 of limits sequentially, we get

$$
\begin{gathered}
\lim _{x \rightarrow 2}\left(3 x^{2}-2 x\right)=\lim _{x \rightarrow 2}\left(3 x^{2}\right)-\lim _{x \rightarrow 2}(2 x)=3 \lim _{x \rightarrow 2} x^{2}-2 \lim _{x \rightarrow 2} x= \\
=3\left(\lim _{x \rightarrow 2} x\right)^{2}-2 \lim _{x \rightarrow 2} x=3 \cdot 2^{2}-2 \cdot 2=8 .
\end{gathered}
