Write as an Equation f(x)=3x+ square root of 4-2

$f (x) = 3 x + \sqrt{4} - 2$

Step 1

Rewrite the function as an equation.

$y = 3 x + \sqrt{4} - 2$

Step 2

Simplify $3 x + \sqrt{4} - 2$ .

Simplify each term.

Rewrite $4$ as $2^{2}$ .

$y = 3 x + \sqrt{2^{2}} - 2$

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

$y = 3 x + 2 - 2$

Combine the opposite terms in $3 x + 2 - 2$ .

Subtract $2$ from $2$ .

$y = 3 x + 0$

Add $3 x$ and $0$ .

$y = 3 x$
