Front

What are the coordinates of a point in a Cartesian plane?

Back

The coordinates of a point are represented as (x, y), where x is the horizontal value and y is the vertical value.

Front

Is the relation shown a function if each input has exactly one output?

Back

Yes, a relation is a function if each input (x-value) corresponds to exactly one output (y-value).

Front

What type of slope does a horizontal line have?

Back

A horizontal line has a slope of zero.

Front

What type of slope does a vertical line have?

Back

A vertical line has an undefined slope.

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 does it mean if a function is not a one-to-one function?

Back

If a function is not one-to-one, it means that at least one output value is associated with more than one input value.

Front

How do you determine if a relation is a function using the vertical line test?

Back

If a vertical line intersects the graph of the relation at more than one point, then the relation is not a function.

Front

What is the difference between domain and range?

Back

The domain is the set of all possible input values (x-values), while the range is the set of all possible output values (y-values).

Front

What does a positive slope indicate about a line?

Back

A positive slope indicates that as the x-values increase, the y-values also increase.

Front

What does a negative slope indicate about a line?

Back

A negative slope indicates that as the x-values increase, the y-values decrease.
