The graph shown here is the graph of which of the following rational functions?
A. F(x) = x + 1/x-1
B. F(x) = x-1/x+1
C. F(x) = 1/(x-1)(x+1)

-18

step-by-step explanation:

because mean value defines that total sum value over total number of set

(d)

step-by-step explanation:

given: the line in the graph passes through points (5,30) and (6,26).

then, the equation of line is:

now, put y=a(n) and x=n,

hence, option d is correct.
