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.

Wait, what’s the question type it in the comments here and I’ll answer!!
X - 2 = - 2x + 7
3x = 9
x = 3
f(x) = g(x) when x = 3.
I’m sorry but you didn’t show the answers possiblites so I can’t answer your question
Answer:
C
Step-by-step explanation:
2x+3x Have the same variable. Therefore they both have like terms
