Module 3 Test (Math 1)

Front

What is the Range of a function?

Back

The Range of a function is the set of all possible output values (y-values) that the function can produce.

Front

What is the minimum point of a graph?

Back

The minimum point of a graph is the lowest point on the graph, representing the smallest value of the function.

Front

How can you determine if a set of ordered pairs is a function?

Back

A set of ordered pairs is a function if each input (x-value) is associated with exactly one output (y-value). If any x-value is repeated with different y-values, it is not a function.

Front

What is the range of the relation: (9, -2), (4, 3), (8, 10), (-4, 8)?

Back

The range is the set of y-values: {-2, 3, 8, 10}.

Front

What is the definition of the range in a relation?

Back

The range is the set of all y-values in a relation.

Front

What does it mean for a function to be linear?

Back

A linear function is a function that graphs to a straight line, which can be expressed in the form y = mx + b, where m is the slope and b is the y-intercept.

Front

What is the slope of a line?

Back

The slope of a line is a measure of its steepness, calculated as the change in y divided by the change in x (rise/run).

Front

What is a vertical line test?

Back

The vertical line test is a method to determine if a graph represents a function. If any vertical line intersects the graph at more than one point, it is not a function.

Front

What is an ordered pair?

Back

An ordered pair is a pair of numbers used to represent a point in a coordinate system, typically written as (x, y).

Front

What is the y-intercept of a linear function?

Back

The y-intercept is the point where the graph of the function crosses the y-axis, represented as (0, b) in the equation y = mx + b.
