Answer:

Step-by-step explanation:
The function is given.

To find : 
The input for the function f(x) is (a + 1).
Replace x with (a + 1).

Expand brackets.

Simplifying.

Midpoint formula
for
(x1,y1) and (x2,y2)
the point is
((x1+x2)/2,(y1+y2)/2)
(8,2)
(6,10)
point is
((8+6)/2,(2+10)/2)
(14/2,12/2)
(7,6)
midpoint is (7,6)
