Second batch of limit problems. these don't have graphs but their constraints are confusing. can someone with these ? i need to see how to do the problems, not just answers.

Problem #1:

We are approaching x = -1 from the left, and x is less than -1.  Thus, use f1(x) = x - 5 instead of f2 or f3.

Just before x reaches -1, the value of f1(x) will be just a bit smaller than -1-5, that is, just a bit smaller than -6.  Understanding that x can also equal -1, then the limit of f1(x) as x approaches -1 from the left is -6; it is defined.

Try the next problem.  Share your work.  I'd be happy to give you feedback on your efforts.

Just tell koda to adjust the number of shapes himself.
