Input Output Flashcard Test

Front

What is an input in a function?

Back

An input is the value that is put into a function to get an output.

Front

What is an output in a function?

Back

An output is the result that comes from applying a function to an input.

Front

What does the equation y = x + 5 represent?

Back

It represents a linear function where the output (y) is 5 more than the input (x).

Front

How do you find the output for the function y = 4x when x = 2?

Back

Substitute x with 2: y = 4(2) = 8.

Front

What is a function table?

Back

A function table is a chart that shows how each input is paired with its corresponding output.

Front

What is the rule for the function if the output is always 3 more than the input?

Back

The rule is y = x + 3.

Front

If x = 5 in the function y = x + 5, what is y?

Back

y = 5 + 5 = 10.

Front

What does it mean if a function is linear?

Back

A linear function means that the graph of the function is a straight line.

Front

What is the difference between dependent and independent variables?

Back

The independent variable is the input (x), and the dependent variable is the output (y) that depends on the input.

Front

How can you determine the rule of a function from a table?

Back

Look for a consistent pattern in how the inputs relate to the outputs.
