The positions in which the graph are increasing in interval notation are: [-7, 6] , [1, 10 ] , [6 , 3] .
How to determine the intervals of a polynomial graph.
The intervals of a polynomial graph is the point at which the curve of the graph changes direction. The graph can be an increasing graph or decreasing graph. An increasing graph moves in the upward direction and the slope is positive. A decreasing graph moves in the downward direction and the slope is negative.
The interval of a graph can either be open ended or close ended. The interval of an open ended graph is written using parentheses ( ). The interval of a close ended graph is written using closed brackets [ ].
From the graph, the positions in which the graph are increasing in interval notation are: [-7, 6] , [1, 10 ] , [6 , 3] .
