Evaluate f(x)=3(2)^-1

$f (x) = 3 {(2)}^{- 1}$

Step 1

Simplify $3 \cdot 2^{- 1}$ .

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

$f (x) = 3 \cdot \frac{1}{2}$

Combine $3$ and $\frac{1}{2}$ .

$f (x) = \frac{3}{2}$

Step 2

Subtract $f (x)$ from both sides of the equation.

$0 = \frac{3}{2} - f (x)$

Step 3

Rewrite the equation as $\frac{3}{2} - f (x) = 0$ .

$\frac{3}{2} - f (x) = 0$
