A function expresses the relationship between two or more variables. A function can be expressed as a mathematical equation or as a graph. In general, a function expresses a the effect an independent variable has on the dependent variable.

.

For example, in the classic linear function:

  • y = mx + b

x and y are the variables (m is said to be the slope, and b is the constant). This function expresses the mathematical relationship between the variables x and y. In this function, x is said to be the independent variable, and the function destines the y variable to be dependent upon the value of x.

When an experiment shows that two variable are closely related that experiment shows?

that there is a correlation between the two variables. However, correlation does not imply causation, so it is important to further investigate to determine the nature of the relationship between the variables.


When an experimental shows that one variable makes another variable change and no variables have any affect the experiment shows?

The experiment shows a causal relationship between the two variables, where changes in one variable directly impact the other without interference from any other variables. This suggests a clear cause-and-effect relationship between the variables being studied.
