$f (- 3) = {0.5}^{- 3}$

Step 1

Move $- 3$ to the left of $f$ .

$- 3 f = {0.5}^{- 3}$

Step 2

Rewrite the expression using the negative exponent rule $b^{- n} = \frac{1}{b^{n}}$ .

$- 3 f = \frac{1}{{0.5}^{3}}$

Step 3

Raise $0.5$ to the power of $3$ .

$- 3 f = \frac{1}{0.125}$

Step 4

Divide $1$ by $0.125$ .

$- 3 f = 8$
