What is the domain of a function?

Back

The domain of a function is the set of all possible input values (x-values) for which the function is defined.

Front

What is the range of a function?

Back

The range of a function is the set of all possible output values (y-values) that the function can produce.

Front

What is the difference between a strong positive and a weak positive correlation?

Back

A strong positive correlation (r close to 1) indicates a strong relationship where as one variable increases, the other also increases significantly. A weak positive correlation (r close to 0) indicates a slight relationship.
