The graph is increasing at x > 1.0
The graph is decreasing at x < 1.0
The absolute minimum of the graph is at 3.0
When is a graph increasing and decreasing
A graph is increasing on an interval if, as you move from left to right along the x-axis, the corresponding y-values increase.
From the graph, we have x > 1.0
A graph is decreasing on an interval if, as you move from left to right along the x-axis, the corresponding y-values decrease.
From the graph, we have x < 1.0
The absolute minimum of the graph is the point that has least value. From the graph, the point is at 3.0
