The graph shows the number of associate's degrees earned (in thousands) in the United States from 2000 through 2008. M(x) gives the number of degrees earned by males, $F(x)$ gives the number earned by females, and $T(x)$ gives the total number for both groups. Use the graph. (GRAPH CAN'T COPY). Use the slopes of the line segments to decide in which period $(2000-2004 \text { or } 2004-2008)$ the total number of associate's degrees earned increased more rapidly.

Key Concepts

Piecewise Linear Functions

Piecewise linear functions are functions defined by multiple line segments, each with its own constant slope over specific intervals. Analyzing these segments can help determine different trends or behaviors within different time periods or conditions.

Graphical Data Analysis

Graphical data analysis involves interpreting the information presented in graphs to understand trends and patterns over time. This includes comparing the slopes of line segments to assess rates of change, identifying periods of rapid increase or decrease, and drawing conclusions based on these visual representations.

Rate of Change

The rate of change measures how a quantity changes with respect to another variable, especially over time. In graphical analyses, this is represented by the slope of a line, indicating how rapidly one variable increases or decreases compared to another.

Slope of a Line

The slope is a numerical value that describes the steepness and direction of a line on a graph. It is calculated as the ratio of the vertical change (rise) to the horizontal change (run) between two points, and it helps in comparing different segments or intervals on a graph.
