Investigation 10: Graphing the Slope Function

Carefully examine both the table of values you have created and the graphs of the two functions to analyze any connections.
If you still have trouble making connections, answering the questions below may help.
Determine the intervals of increase and decrease of the graph of the original function.
As well, locate its vertex.
Can you find any connections between your answers to these questions and the values of the y-coordinates of the graph of the slope function?
