Question

What is the equation written in a function notation with x as the independent variable x-y=3

Answer 1

we are given

$x-y=3$

Here , we are given

x as the independent variable

so, y is dependent variable

so, we will solve for y

$x-y=3$

Add both sides by y

$x-y+y=3+y$

$x=3+y$

Subtract both sides by 3

$x-3=3+y-3$

$x-3=y$

so, our function is

$f(x)=x-3$................Answer
