Answer
$-54$
Work Step by Step
Use the limit properties:
$(1) \ \lim\limits_{x \to a} l(x)=l (a) \\ (2) \lim\limits_{x \to a} k(x) l(x)=\lim\limits_{x \to a} k(x) \cdot \lim\limits_{x \to a} l(x)=k(a) \ l(a) $
where $a$ is a constant.
$\lim\limits_{x \to -3} (2x^3)= \lim\limits_{x \to -3} (2) \cdot \lim\limits_{x \to -3} (x^3) \\=(2)(-3)^3\\=(2)(-27)\\=-54$
