Now match the options one by one.

Answer 18

Well it looks like b and c are most similar?

Answer 19

Right! Now your problem says 2 ^3√(x+2)+4

Since it's +4, it should be above the value of zero. As in case of opt 2.

If it were let's say -1, then it would have been below 0 as in opt 3.

Answer 20

So it's b?

Answer 21

Yep!

Answer 22

Thanks!
