Question 291551
Find the average rate of change for the function over the given interval.
y=√2x-1 between x=1 x=5
------------------
{{{y = sqrt(2x-1)}}}
@x = 1, y = 1
@x = 5, y = 3
--------------
diffy = 3-1 = 2
diffx = 5-1 = 4
-----------------
diffy/diffx = 2/4 = 1/2
-------------------------
This is not a linear equation, and the 1/2 is the average rate of change, not valid at any of the points between (1,1) and (5,3)
