In the following graph, state the absolute and local maximum and minimum values of the function.

Explanation

x = 2 is the point of local minima, and the local minimum value is f(2) = 1.
x = 4 is the point of absolute maxima, and the absolute maximum value is f(4) = 4.
x = 5 is the point of local minima, and the local minimum value is f(5) = 2.
x = 6 is the point of local maxima, and the local maximum value is f(6) = 3.
x = 7 is the point of absolute minima, and the local minimum value is f (7) = 0.
