Finding limits when given 2 different limits.
Let lim x 1 f ( x ) = 8 and lim x 1 g ( x ) = 4. Find lim x 1 f ( x ) g ( x )
Answer Choices are:
A. 2
B. 12
C. 1 / 2
D. 1
I started out trying to solve this problem by attempting to use a derivative formula which just overcomplicated the problem and did not lead me to any of the potential answer choices.
I was struggling with this problem as I did not understand the limit laws and upon further review I understood them well enough to realize that I should have just simply plugged in my f ( x ) and g ( x ) values to get my final answer of 2
Is this okay?

Using the limit rules and the help provided by other people I was able to determine that the final answer is -2
I also realize now that I way over thinking this question. It has been a long day of math I am sorry for asking such an obvious one when the answer was as right in front of me in the form of basic math.
