Exploring Algebra2: FUNC Basics and Rational Expressions

What is a function in mathematical terms?

• A device that assigns no values to arguments.

• A device that assigns one value to each argument.

• A device that assigns multiple values to each argument.

• A device that assigns random values to arguments.

Which of the following is NOT a way to represent a function?

• A table of random values

• A set of ordered pairs

• A map

• A rule or formula

What is the purpose of the vertical line test?

• To determine the range of a function.

• To determine if a graph is symmetrical.

• To determine if a graph represents a function.

• To determine the slope of a graph.

How do you apply the vertical line test?

• Move a vertical line from left to right.

• Move a horizontal line from top to bottom.

• Move a diagonal line across the graph.

• Move a curved line across the graph.

What does it mean if a vertical line intersects a graph at more than one point?

• The graph has no range.

• The graph is a function.

• The graph is symmetrical.

• The graph is not a function.

In the vertical line test, what should happen if the graph represents a function?

• The vertical line should intersect the graph at multiple points.

• The vertical line should intersect the graph at random points.

• The vertical line should not intersect the graph at all.

• The vertical line should intersect the graph at exactly one point.

What can be concluded if a graph passes the vertical line test at every point?

• The graph is not a function.

• The graph is a function.

• The graph is symmetrical.

• The graph has no domain.

What happens if a graph fails the vertical line test at any point?

• The graph has no range.

• The graph is still a function.

• The graph is not a function.

• The graph is symmetrical.

Why does a graph fail the vertical line test?

• Because the vertical line intersects the graph at random points.

• Because the vertical line intersects the graph at exactly one point.

• Because the vertical line does not intersect the graph at all.

• Because the vertical line intersects the graph at multiple points.

Which of the following statements is true about a graph that passes the vertical line test?

• It has no domain.

• It is symmetrical.

• It is a function.

• It is not a function.
