The intervals indicated on the graph are:
-7 < x < -3, -3 < x < -1, & 1 < x < 3 are increasing
-1 < x < 1, & 3 < x < 5 are decreasing
5 < x < 7 is neither
When does an Interval of a Function Decrease or Increase?
The interval of a function is increasing when the line slopes upward to the right along the interval. This means that the function value would increase as the input values decrease within the given interval.
On the other hand, the interval decreases when the line of the function slopes downwards within the interval. This implies that as the function value decreases, the input values increase within the given interval.
Therefore, from the graph given, we can conclude that:
-7 < x < -3: increasing
-3 < x < -1: increasing
-1 < x < 1: decreasing
1 < x < 3: increasing
3 < x < 5: decreasing
5 < x < 7: neither
