The initial value of the graph is where . Thus, in this case, the initial value is 12.
The rate of change of the graph is essentially the slope of the graph. In this case, we can use the slope formula:
and
are points on the graph
Let's use two points from the chart to find the slope:
In this case, the rate of change of the graph is 9.
