I had a typo at the end of the first line; it should have been f(x) dx. I could have gone from there to say ∫0 to 2 -f(x) dx + ∫0 to 2 f(x) dx = -∫0 to 2 f(x) dx + ∫0 to 2 f(x) dx = 0 * ∫0 to 2 f(x) dx = 0 because ∫0 to 2 f(x) dx exists.

The argument shown works as well because f is integrable on -2 to 2
