Answer:
HMMMMM
Step-by-step explanation:
The value could be rewritten as 2(x+4)
Answer: b ≤ -18
<u>Step-by-step explanation:</u>
Isolate the variable by multiplying both sides by -3. Remember that when you multiply or divide by a negativem the symbol flips.

I assume you mean f(x) = (x+1) / (x^2 - 6x + 8)
Then f(x) = (x+1)/ (x-2)(x-4)
So the domain will be all real numbers except 2 and 4
