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.
e2π+1=0
