Table of Values

Front

What is a table of values?

Back

A table of values is a chart that shows the relationship between two variables, typically input (x) and output (y), by listing pairs of values.

Front

What does the ordered pair (x, y) represent?

Back

An ordered pair (x, y) represents a point on a graph where 'x' is the input value and 'y' is the output value.

Front

If the function rule is y = 2x, what is the output when x = 3?

Back

The output is 6, because y = 2(3) = 6.

Front

What is the function rule for the output if the input is increased by 5?

Back

The function rule can be expressed as y = x + 5.

Front

How do you find the output using a function rule?

Back

To find the output, substitute the input value into the function rule and calculate the result.

Front

What is the output if the function rule is y = x - 4 and the input is 10?

Back

The output is 6, because y = 10 - 4 = 6.

Front

What does it mean if a function is linear?

Back

A linear function means that the relationship between the input and output can be represented by a straight line on a graph.

Front

If the function rule is y = 3x + 1, what is the output when x = 2?

Back

The output is 7, because y = 3(2) + 1 = 7.

Front

What is the input if the output is 15 and the function rule is y = 5x?

Back

The input is 3, because 15 = 5x, so x = 15/5 = 3.

Front

What is the output if the function rule is y = x + 8 and the input is 5?

Back

The output is 13, because y = 5 + 8 = 13.
