So as long as x does not equal 2, these two things will cancel out. So we could say this is equal to x plus 3 for all x's, except for x is equal to 2, as long as x does not equal 2. So that's another way of looking at it. Another way we could rewrite our f of x. I'm doing it in blue just to change the colors. We could rewrite f of x. This is the exact same function. f of x is equal to x plus 3 when x does not equal 2.
