What is a function?

Back

A function is a relation that assigns exactly one output for each input. In other words, for every input value (x), there is one and only one output value (y).

What is the general form of a linear function?

How do you represent total cost in a function?

Front

What does the slope of a linear function represent?

Back

The slope of a linear function represents the rate of change of the output value with respect to the input value.

Front

What is the y-intercept in a function?

Back

The y-intercept is the value of the function when the input (x) is zero. It is the point where the graph intersects the y-axis.

Front

How can you determine if a set of ordered pairs is a function?

Back

A set of ordered pairs is a function if no two pairs have the same first element (x-value) with different second elements (y-values).

Front

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

Back

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

Front

What is the domain of a function?

Back

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

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

How do you evaluate a function at a specific point?

Back

To evaluate a function at a specific point, substitute the input value into the function's equation and solve for the output.
