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.
What else can I help you with?
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?
The strength and the direction of a relationship.
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?
A correlation reflects the strength of the relationship between two variables. A correlation doesn't reflect causation, but merely that two phenomena are present at the same time. The closer the value is to 1, the stronger the relationship between two variables is. This value can be positive or negative. A negative value merely indicates that, as the values on one variable increase, the values on the second variable decrease. A positive correlation indicates that both values will increase or decrease together.
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?
Function
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 an equation that expresses a relationship between two or more quantities?
an equation that expresses a relationship between two or more quantities
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 the ratio of two quantities that change?
It is a non-linear or non-existent relationship between the two quantities.
What is a relationship between two quantities in which the ratio of one quantity to other quantity is constant?
It is called direct variation.
What compares or show the relationship between two quantities?
It is a ratio
What is the rule that establishes a relationship between two quantities?
Function
4 kinds of relationships between the physical quantities?
Direct relationship: When two quantities increase or decrease together. Inverse relationship: When one quantity increases while the other decreases. Linear relationship: When the relationship between the quantities can be represented by a straight line. Nonlinear relationship: When the relationship between the quantities cannot be represented by a straight line.
What is compound proportion?
Compound proportion refers to a mathematical relationship between two ratios where multiple quantities are compared. It involves comparing multiple ratios involving more than two quantities in a proportional relationship.
