Checkpoint Flashcard 9

Front

What is the relationship between x and y in a function?

Back

In a function, for each x (input), there is only one corresponding y (output).

Front

What does it mean when a graph is increasing?

Back

An increasing graph means that as the x-values increase, the y-values also increase.

Front

What does it mean when a graph is decreasing?

Back

A decreasing graph means that as the x-values increase, the y-values decrease.

Front

What is a straight line graph with no increase or decrease called?

Back

It is called a constant function.

Front

If a function is represented as y = mx + b, what do m and b represent?

Back

m represents the slope of the line, and b represents 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 rise over run.

Front

What is a linear function?

Back

A linear function is a function that graphs to a straight line.

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 does it mean for a function to be one-to-one?

Back

A function is one-to-one if each y-value corresponds to exactly one x-value.

Front

What is the domain of a function?

Back

The domain of a function is the set of all possible input values (x-values).
