Question
For each of the following graphs, use interval notation to express the values of x on which the graph is:
- the value of the function is increasing
- the value of the function is decreasing
- the rate of change of y with respect to x is increasing
- the rate of change of y with respect to x is decreasing
Write DNE if there are no intervals of x which satisfy the description.
The graphs, from left to right, are A,B, and C.
