#### Answer

When $x=-2$: $-\frac{1}{3}$
When $x=0$: $-1$
When $x=2$: $-3$

#### Work Step by Step

For $x=-2$:
$-3^{0.5 * -2}$ = $-3^{-1}$ = -$\frac{1}{3^{1}}$ = -$\frac{1}{3}$
For $x=0$:
-$3^{0.5*0} = -1$;
(Any nonzero raised to the 0 power is equal to 1)
For $x=2$:
$3^{0.5 * 2}$ = $3^{1}$ = $\frac{1}{3^{1}}$ = $\frac{1}{3}$
