Function Tables

Front

What is a function table?

Back

A function table is a chart that shows how one quantity depends on another. It lists pairs of input and output values.

What is an input in a function table?

Back

An input is the value you put into a function to get an output. It is usually represented in the first column of a function table.

Front

What is an output in a function table?

Back

An output is the result you get after applying a function to an input. It is usually represented in the second column of a function table.

What does it mean to find a missing input in a function table?

Back

Finding a missing input means determining the value that, when used in the function, will produce a known output.

Front

What is a rule in a function table?

Back

A rule is a mathematical expression that describes the relationship between the input and output values in a function table.

Front

How do you write an equation from a function table?

Back

To write an equation, identify the relationship between inputs and outputs, and express it in the form of 'output = function(input)'. For example, if the output is always 3 more than the input, the equation is 'output = input + 3'.

What does 'b = a + 13' mean in a function table?

Back

It means that for every value of 'a', the corresponding value of 'b' is 13 more than 'a'.

Front

What does 'f = e x 6' indicate?

Back

It indicates that the output 'f' is six times the input 'e'.

If the equation is k = j - 20, how do you find k when j is 58?

Back

Substitute 58 for j: k = 58 - 20, so k = 38.

What is the purpose of using function tables?

Back

Function tables help visualize and understand the relationship between variables, making it easier to solve problems involving functions.
