Evaluate f(x)=2 square root of 0

$f (x) = 2 \sqrt{0}$

Step 1

Simplify $2 \sqrt{0}$ .

Rewrite $0$ as $0^{2}$ .

$f (x) = 2 \sqrt{0^{2}}$

Multiply by zero.

Pull terms out from under the radical, assuming positive real numbers.

$f (x) = 2 \cdot 0$

Multiply $2$ by $0$ .

$f (x) = 0$

Step 2

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

$0 = - f (x)$

Step 3

Rewrite the equation as $- f (x) = 0$ .

$- f (x) = 0$
