Google has my particular homework online. I am doing 1.5.6, 1.5.7, 1.5.8(adsbygoogle = window.adsbygoogle || []).push({});

On 1.5.6 a), I created a function f(x) such that {a} if x = a, {b} if x = b, {c} if x=c. This is 1-1 since each element of A gets mapped to something different. Its obviously not onto.

Skipping down to 1.5.7, I need to create the set B for this function. For any a, it cant be an element of f(a). Does this mean B = the empty set?

If so, I think I can tackle the rest...
