Answer: First option.

Explanation:

Given the equation
y-x-4=0 , you need to substitute
f(x)=y into this equation. Then:

f(x)-x-4=0

Remember that the Addition property of equality states that:

$If\ a=b\\then\ a+c=b+c$

Then, you can add "x" and 4 to both sides.

Therefore, you get the equation written in function notation, with "x" as the independent variable:

$f(x)-x-4+(4)+(x)=0+(4)+(x)\\f(x)=x+4$
