the graph increases when the values in y are increasing
we must mention the part of x where the function increases
so
Increassing:
[tex](-\infty,1)[/tex]because the graph is increasing from a very small number to the number 1
the graph decreases when the values in and are less and less
we must mention the part of x where the function decreasing
so
Decreasing:
[tex](1,\infty)[/tex]because the graph starts to decrease from the number 1 to a very large number
the range is the part of y that the graph uses, from the lowest point to the highest
Range:
[tex](-\infty,2\rbrack[/tex]because the smallest number is a very small number and the largest number that takes in y is 2
