ALGEBRA Mixed Review Unit 4

Front

What is a piecewise function?

Back

A piecewise function is a function that is defined by different expressions or rules for different parts of its domain.

Front

How do you determine if a relation is a function?

Back

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

Front

What does it mean for a function to be undefined at a certain point?

Back

A function is undefined at a certain point if there is no corresponding output (y-value) for that input (x-value).

Front

What is the significance of the x-values in a function?

Back

The x-values (inputs) determine the corresponding y-values (outputs) in a function.

Front

How can you identify a function from a table of values?

Back

You can identify a function from a table of values by checking if any x-value is repeated with different y-values.

Front

What is the graphical representation of a function?

Back

The graphical representation of a function is a curve or line on a coordinate plane that shows the relationship between x and y.

Front

What does it mean for a function to have a slope?

Back

The slope of a function represents the rate of change of the y-value with respect to the x-value.

Front

How do you evaluate a function at a specific point?

Back

To evaluate a function at a specific point, substitute the x-value into the function's equation and solve for the y-value.

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.

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 has at least one input with multiple outputs.
