Analyze Functional Relationships

What information about a function is NOT provided by a qualitative description?

• The direction of the graph in each interval or section

• The rate of change for each linear section of the graph

Arrange the qualitative description of the function.

• I, II, III

• I, II, IV

• II, I, III

• II, I, IV
