Algebra 1 MCAP Review #2

Front

What is a function?

Back

A function is a relation where each input (x-value) has exactly one output (y-value).

Front

How can you tell if a relation is a function?

Back

A relation is a function if no x-value is repeated with different y-values.

Front

What is the definition of the range in a function?

Back

The range is the set of all possible output values (y-values) of a function.

Front

What is the y-intercept of a function?

Back

The y-intercept is the point where the graph of the function crosses the y-axis, represented as (0, y).

Front

What does it mean if a function has a repeated x-value?

Back

If a function has a repeated x-value with different y-values, it is not a function.

Front

What is an ordered pair?

Back

An ordered pair is a pair of numbers (x, y) that represents a point on a graph.

Front

What is the domain of a function?

Back

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

Front

How do you find the range of a linear function?

Back

To find the range of a linear function, identify the minimum and maximum y-values that the function can output.

Front

What is the difference between a function and a non-function?

Back

A function has one output for each input, while a non-function can have multiple outputs for the same input.

Front

What is a linear function?

Back

A linear function is a function that graphs to a straight line and can be expressed in the form y = mx + b.
