Evaluate the Function f(0)=2 square root of x

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

Replace the variable $x$ with $0$ in the expression.

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

Simplify the result.

Remove parentheses.

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

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

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

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

$f (0) = 2 \cdot 0$

Multiply $2$ by $0$ .

$f (0) = 0$

The final answer is $0$ .

$0$
