810 Module 6 Test Review

Front

What is a function?

Back

A function is a relation where each input has exactly one output.

Front

How can you determine if a graph is a function?

Back

You can use the vertical line test: if any vertical line intersects the graph more than once, it is not a function.

Front

What is the vertical line test?

Back

The vertical line test is a method to determine if a graph represents a function by checking if vertical lines intersect the graph more than once.

Front

What does it mean for a graph to be linear?

Back

A linear graph is a straight line that represents a constant rate of change.

Front

Which of the following is a characteristic of a function?

Back

Each input (x-value) must correspond to exactly one output (y-value).

Front

What is the definition of a linear function?

Back

A linear function is a function that can be graphically represented as a straight line.

Front

What is the slope of a line?

Back

The slope is a measure of the steepness of a line, calculated as the rise over run.

Front

What is the y-intercept of a graph?

Back

The y-intercept is the point where the graph crosses the y-axis.

Front

What is a non-linear function?

Back

A non-linear function is a function that does not create a straight line when graphed.

Front

How do you identify a linear equation?

Back

A linear equation can be identified by its standard form: y = mx + b, where m is the slope and b is the y-intercept.
