Answer:
5 is the answer
Option C is right answer
Explanation:
Limit is defined as the value which the funciton f(x) approaches as x approaches a certain value.
There are left and right limits.
We have to find out the limit of sum of functions f and g as x tends to 4.
limit x tends to 4 of (f+g)(x) = limit x tends to 4 of (f)(x)+limit x tends to 4 of (g)(x)
Hence required limit = limit of f(x) + limit of g(x)
The above two are given in the question as 5 and 0
Hence adding we get answer =5
Option c is right
