Answer

Final Answer: $f(x)= \boxed{-\frac{7x}{3}}$

Steps

Step 1 ：Consider the following relation: $2x - y = -5x - 4y$

Step 2 ：Rewrite the relation as a function of x.

Step 3 ：To do this, we need to isolate y on one side of the equation.

Step 4 ：The solution to the equation when solved for y is $-\frac{7x}{3}$.

Step 5 ：This means that the function of x, f(x), is $-\frac{7x}{3}$.

Step 6 ：Final Answer: $f(x)= \boxed{-\frac{7x}{3}}$
