Let a and b be sets. prove that (a) acb aub=b; (b) acb = anb = a.

For part (a) and (b) suposse .

To prove part (a) observe that we already have that . So we will prove that . Let , then or . If   we finish the proof, and if implies   because we assume , and the proof is complete.

For part (b) we always have . We finish the proof showing . Let , then by the asumption that . So, we have both and  , that implies . Therfore , which completes the proof.

the answer is d on edge

step-by-step explanation:

answer: yes, since the line has a steeper rate of change than the exponential the y-values will be greater and they will only intersect one time.
