According to the graph:
There is a local minimum at (2,2)
Local maximum at (-1,4) and (5,5)
The function is decreasing in the interval:
[tex]{}[-1,2]\text{ and \lbrack5,}\infty][/tex]
The function is increasing in the interval:
[tex][-\infty,-1]\text{ and \lbrack2,5\rbrack}[/tex]
Answer:
Local minimum: (2,2)
Local maximum: (-1,4) and (5,5)
Decreasing: [-1, 2] and [5, ∞]
Increasing: [ - ∞, - 1] and [2, 5]
