3.1 XY Tables

Front

What is an XY table?

Back

An XY table is a table that displays pairs of input (X) and output (Y) values, often used to represent a function.

Front

How do you find the output of a function given an input?

Back

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

Front

What is the purpose of a function rule?

Back

A function rule defines the relationship between input and output values.

Front

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

Back

Output refers to the result obtained after applying the function rule to an input value.

Front

How can you find a missing output value in an XY table?

Back

You can find a missing output value by using the function rule or equation that relates the inputs and outputs.

Front

What is the equation q = r + 15 used for?

Back

This equation is used to find the value of q when the value of r is known.

Front

If r = 11, what is the value of q in the equation q = r + 15?

Front

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

Back

The relationship is defined by the function rule, which determines how each input corresponds to an output.

Front

What does it mean to match a graph to a table?

Back

It means to identify which graph accurately represents the data or function shown in the table.
