A linear function consists of one independent variable and one dependent variable. 'y' is the dependent variable, while 'x' is the independent variable. In economics, the linear function is popular. It is appealing because it is straightforward and straightforward mathematical. Moreover, it has numerous useful applications. For example, linear functions have graphs that are straight lines.
A linear function's domain and range are typically a set of real numbers. However, there is one exception: if the function is constant (for example, f(x) = 2), the range is constrained to that constant.
