Hello everyone i'm reviewing for the exam and I got 0 points on this proof and it seems like a nice exam question. So i want to make sure I have the correct proof to study.(adsbygoogle = window.adsbygoogle || []).push({});

I don't see how this is wrong when he did a proof such as this one, in almost the same way as mine:

Any help with correcting my above proof so I may study off it would be great!

Note: he did not correct these, the TA did.
