Function Tables

Front

What is a function table?

Back

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

Front

What does the term 'output' mean in a function table?

Back

The output is the result of applying the function rule to the input value.

If y = 2x + 3, what is the output when x = 4?

Back

y = 2(4) + 3 = 8 + 3 = 11.

Front

What is the rule in the function table if the output is always 5 more than the input?

Back

The rule is y = x + 5.

Front

How do you find a missing output value in a function table?

Back

Substitute the input value into the function rule to calculate the output.

Front

What is the function of the table if y = 3x - 2?

Back

The function describes a linear relationship where the output is three times the input minus two.

Front

What does 'y = x + 4' represent in a function table?

Back

It represents a linear function where the output is always 4 more than the input.

Front

If the input is 0 in the function y = 10 - x, what is the output?

Back

The output is 10 - 0 = 10.

Front

What is the output when x = -1 in the function y = x * 2 + 1?

Back

y = -1 * 2 + 1 = -2 + 1 = -1.

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.
