What is a function table?

Back

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

What is the function rule in the equation y=3x+1?

Back

The function rule is a mathematical expression that defines the relationship between input (x) and output (y). In this case, for every input x, the output y is calculated by multiplying x by 3 and then adding 1.

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

What does the term 'input' refer to in a function?

Back

The input is the value that is put into a function to determine the output.

Front

What does the term 'output' refer to in a function?

Back

The output is the value that results from applying the function rule to the input.

Front

How do you find the output of a function?

Back

To find the output, substitute the input value into the function rule and perform the calculations.
