It depends on the direction of the relationship.
Consider y = x2 where x is a real number.
The relationship from x to y is a function but the one in the opposite direction (x = sqrt(y) is not a function because it is a one-to-many mapping.

The relationship between two quantities that increase or decrease together is called what?
The relationship between two quantities that increase or decrease together is called a positive correlation. This means that as one quantity increases, the other quantity also increases, and vice versa.
What is a relationship between two variables or sets of data is called what?
Correlation
What are the two things A correlation coefficient represents?
A correlation coefficient represents the strength and direction of the relationship between two variables. It measures how closely the two variables are related to each other.
What is illusory correlation?
Illusory correlation refers to the perception of a relationship between two variables that does not actually exist. This can occur when rare events are paired together in a person's mind, leading to the mistaken belief that there is a causal connection between them. In reality, the correlation is just a product of coincidence or bias.
What does the value of a correlation coefficent reflects?
The value of a correlation coefficient reflects the strength and direction of the relationship between two variables. A correlation coefficient ranges from -1 to 1, with 1 indicating a perfect positive relationship, 0 indicating no relationship, and -1 indicating a perfect negative relationship.
What is the simplified proportional relationship called?
A proportional relationship between two quantities is one in which the two quantities called the unit rate, the rate of change, or the constant of proportionality.
What is a relationship between two quantities called input and output?

What is the relationship between two quantities for each input there is exactly one output.?
The relationship is called a surjection or a surjective function.
What shows the relationship between two quantities?
A ratio shows the relationship between two quantities.Formula
What is a relationship between two quantities in which the ratio of one quantity to the other is constant?
It is called direct variation.
What is the ratio of two quantities that change?
It is a non-linear or non-existent relationship between the two quantities.
