Answer:
Step-by-step explanation:
We want to evaluate the following limit.
We need to recall that, limit of a sum is the sum of the limit.
So we need to find each individual limit and add them up.
Recall that, as and the limit of a constant, gives the same constant value.
This implies that,
This gives us,
The correct answer is D
