Function Tables Practice

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 function or rule.

Front

What does the function rule y = x - 10 represent?

Back

This function rule indicates that for every input x, the output y is 10 less than x.

Front

If the function rule is y = x ÷ 3, what is the output when the input is 9?

Back

The output is 3, because 9 ÷ 3 = 3.

Front

What is the output if the input is 4 and the function rule is y = 5x?

Back

The output is 20, because 5 * 4 = 20.

Front

How can you determine if a table represents a function?

Back

A table represents a function if each input corresponds to exactly one output.

Front

What is the difference between input and output in a function?

Back

Input is the value you put into a function, while output is the value you get out after applying the function rule.

Front

If the function rule is y = 4x, what is the output when the input is 3?

Back

The output is 12, because 4 * 3 = 12.

Front

What does it mean for a mapping to represent a function?

Back

A mapping represents a function if each element in the domain (input) is paired with exactly one element in the range (output).

Front

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

Back

The output is 6, because 2 * 3 = 6.

Front

What is the output if the input is 10 and the function rule is y = x - 14?

Back

The output is -4, because 10 - 14 = -4.
