Consider the function f(x)=5x−4 and find the following:
a.) The average rate of change between the points (−1,f(−1)) and (2,f(2)).
b.) The average rate of change between the points (a,f(a)) and (b,f(b)).
c.) The average rate of change between the points (x,f(x)) and (x+h,f(x+h)).
For a linear function average rate of change is always equal at any point on the graph.
