Write as a Function of x y-x-4=0

$y - x - 4 = 0$

Step 1

Move all terms not containing $y$ to the right side of the equation.

Add $x$ to both sides of the equation.

$y - 4 = x$

Add $4$ to both sides of the equation.

$y = x + 4$

Step 2

To rewrite as a function of $x$ , write the equation so that $y$ is by itself on one side of the equal sign and an expression involving only $x$ is on the other side.

$f (x) = x + 4$

Write as a Function of x y-x-4=0
