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 based on its domain.

Front

How do you express the range of a function using inequalities?

Back

Front

What is the independent variable in a function?

Back

The independent variable is the input value that can be changed freely, often represented as x. It determines the output of the function.

Front

What is the dependent variable in a function?

Back

The dependent variable is the output value that depends on the independent variable, often represented as y.

Front

What is a linear function?

Back

Front

How do you find the cost function for a service with a fixed fee and a variable rate?

Back

Front

What is the maximum value of a function?

Back

The maximum value of a function is the highest output value it can produce, often found at the endpoints of the domain or at critical points.

Front

What is the minimum value of a function?

Back

The minimum value of a function is the lowest output value it can produce, also found at the endpoints of the domain or at critical points.

Front

How do you determine the domain of a function?

Back

The domain of a function is the set of all possible input values (x-values) that the function can accept without resulting in undefined expressions.

Front

What is a step function?

Back

A step function is a piecewise constant function that jumps from one value to another, often used to model situations with fixed intervals.
