The document provides information about key concepts related to functions including intercepts, domains, relations, and sequences. It defines x-intercepts and y-intercepts as the points where a function graph crosses the x or y-axis. It asks the reader to find intercepts and function values for given graphs, write rules and sketch graphs for relations, and determine if a relation is a function. It also includes examples of numeric sequences and asks the reader to find the next few terms.

2. Intercepts
• The x-intercepts of a
function are the x-coordinates
of the points where the graph
of the function intersects the
x-axis.
• The y-intercept of a
function is the y-coordinate
of the point where the
graph of the function
intersects the y-axis.

3. Given the graph of the function g find the value of:
g(0) =
g(1) =
g(-2) =
g(3) =
Identify all intercepts.

4. The domain of a relation is the set of real numbers. The following
are some of the ordered pairs associated with the relation.
Write a rule (equation) Sketch the graph.
for this relation.
Is it a function?
