Answer:
5x+2
Step-by-step explanation:
Answer:
Answer to all three points is NO.
Step-by-step explanation:
Case 1:

Answer : NO, It is important to note that the even if function is not defined, the limit of function can exist and it doesn't mean that f(x) must necessarily be defined at x = 1
Case 2:
Answer : No, because it could be a piece wise function even if f is defined, where f(1) might have different values while approaching from right and left side of limits.
Case 3:
Answer: No, value of f(1) can not be concluded
So,
2x + 6 - 6x = 30
Collect Like Terms.
-4x + 6 = 30
Subtract 6 from both sides.
-4x = 24
Divide both sides by -4.
x = -6
Check.
2x + 6 - 6x = 30
2(-6) + 6 - 6(-6) = 30
-12 + 6 + 36 = 30
-6 + 36 = 30
30 = 30 This checks.
S = {-6}
That is option A.
