One-to-one: A function is said to be one-to-one if every y value has exactly one x value mapped onto it.
Many-to-one: If there are y values that have more than one x value mapped onto them.
One-to-many: If there are x values that have more than one y value mapped onto them. (NOT A FUNCTION)
Many-to-many: If there are x values that have more than one y value mapped onto them and at the same time, there are y values that have more than one x value mapped onto them (NOT A FUNCTION)
From all the ordered pairs, we find that the points (1,2) and (1,3) have the same x-value for diferent y-values. Also we find that the points (1,2) and (-2, 2) have different x-values for the same y-value.
Therefore, the ordered pairs DO NOT belong to a function and can be considered MANY-TO MANY.
The interior angle of a regular polygon is equal to each other since all sides of the polygon are congruent. The formula that expresses the relation of the sides of the polygon and the measurement of the interior angle is (n2)*180/n where n is 7. Each interior angle then measures 128.6 degrees.
