The average rate of change of the function is -1/3
Rate of change of a function
The rate of change of a function is expressed as;
f'(x) = f(b)-f(a)/b-a
From the given graph, we are
f(b) = f(4) = 0
f(a) = f(1) = 1
Substitute the given parameters into the formula
f'(x) = f(4)-f(1)/4-1
f'(x) = 0-1/4-1
f'(x) = -1/3
Hence the average rate of change of the function is -1/3
