Weighted average is more complicated to calculate than arithmetic. As the name suggests, in the weighted average the various numbers have different relative values, or weights. For example, this average can be useful if you are trying to calculate your grade in a class where the various tests contribute different percentages to the final grade.
Each function contains two types of variables: independent and dependent ones, the value of the latter literally "depends" on that of the former. For example, in the function y = f (x) = 2 x + y, x is the independent variable and y is dependent (in other words, y is a function of x).
