Front

What is a function table?

Back

A function table is a chart that shows how each input (x) is related to an output (y) through a specific function or rule.

Front

What does the equation y = x + 8 represent?

Back

It represents a linear function where the output (y) is 8 more than the input (x).

Front

If x = 5 in the equation y = x + 8, what is y?

Back

y = 5 + 8 = 13.

What is the purpose of a function in mathematics?

Back

A function describes a relationship between two quantities, where each input is related to exactly one output.

Front

What does the equation y = x - 6 mean?

Back

It means that the output (y) is 6 less than the input (x).

Front

If x = 12 in the equation y = x - 6, what is y?

Back

y = 12 - 6 = 6.

Front

What is the output when x = 4 in the equation y = x + 5?

Back

y = 4 + 5 = 9.

Front

How do you find the missing number in a function table?

Back

You substitute the given input (x) into the function's equation to find the corresponding output (y).

Front

What is the equation for a function that doubles the input?

Back

y = 2x.

Front

If y = 3x + 1, what is y when x = 2?

Back

y = 3(2) + 1 = 7.
