Exploring Functions in 8.5G

Both x and y values must be positive.

Each x value must be unique.

The ordered pairs must form a straight line.

Each y value must be unique.

If the y values are not in ascending order

If it forms a straight line on a graph

If any x value appears more than once

If it includes both positive and negative numbers

There can be multiple x values for one y value.

There can be multiple y values for one x value.

Each x value corresponds to exactly one y value.

Each y value corresponds to exactly one x value.

A function where the graph is a straight line

A function with only positive x values

A function where each x value has multiple y values

A function that includes only whole numbers

Repeated y values

Decimal numbers

Negative numbers

Repeated x values

They cannot be zero

They must be in ascending order

To determine if a graph represents a linear function

To find the slope of a graph

To measure the distance between points on a graph

To check if a graph represents a function

It represents a function

All its values are positive

It has repeated x values

It does not represent a function

It means the function cannot have negative values

It is necessary for the function to have a graph

It ensures the function is linear

It is a rule to determine if a relationship is a function
