Respuesta :

we are given

[tex]x-y=3[/tex]

Here , we are given

x as the independent variable

so, y is dependent variable

so, we will solve for y

[tex]x-y=3[/tex]

Add both sides by y

[tex]x-y+y=3+y[/tex]

[tex]x=3+y[/tex]

Subtract both sides by 3

[tex]x-3=3+y-3[/tex]

[tex]x-3=y[/tex]

so, our function is

[tex]f(x)=x-3[/tex]................Answer
