The average rate of change for a function between two points is the slope of the secant line that contains the two points.

f(2)=2(2)^+10=18

f(5)=2(5)^+10=60

Therefore the two points are (2,18)  and (5,60)

Use the slope formula:

m=y1-y2/x1-x2

where (x1,y1) and (x2,y2) are the coordinates of the given points.
