Analyzing Functions
Standard(s): 8.F.B.5
The graph of a linear function lies in the first and third quadrants. Which of the following must be true?
It also lies in the second quadrant.
It also lies in the fourth quadrant.
It is an increasing function.

Standard: 8.F.B.5
Domain: Functions
Theme: Use functions to model relationships between quantities
Description: Describe qualitatively the functional relationship between two quantities by analyzing a graph (e.g., where the function is increasing or decreasing, linear or nonlinear). Sketch a graph that exhibits the qualitative features of a function that has been described verbally.
The graph of a decreasing linear function crosses the vertical axis at (0, 3). Which of the following CANNOT be true?
The graph lies in the first quadrant.
The graph lies in the second quadrant.
The graph lies in the third quadrant.
The graph lies in the fourth quadrant.
