To identify:
Local
Given information:
The graph
Calculation:
There are local maxima at (−1,4) and (5,5) because the function increases to those points and decreases after them.
There is a local minimum at (2,2) because the function decreases to that point and increases after it.
The function increases on (−∞,−1] , decreases on [−1,2] , increases on [2,5] and decreases on [5,∞) .
Therefore, Local maxima at (−1,4) and (5,5) , local minimum at (2,2) . The function increases on (−∞,−1] , decreases on [−1,2] , increases on [2,5] and decreases on [5,∞) .
