Use the arrow diagram below to find π by π.
We want to find a list of ordered pairs describing the relationship between π and π. If we start here, where π is four, when π is four, π can be nine. When π is four, π can also be three. And when π is four, π equals eight. When our π coordinateβs four, we have three ordered pairs: four, nine; four, three; and four, eight.
We should follow the same process when our π equals zero. When our π is zero, we can have zero, nine or zero, three or zero, eight.
The set of all the relationships between π and π would look like this: four, nine; four, three; four, eight; zero, nine; zero, three; zero eight.
