👉 In mathematics, a lineary function is a mathematical function that can be represented as a straight line on a graph. It has one input and one output variable, with each input value contributing to the output of the function in some way. The concept of linearity can also refer to the fact that functions that are linearly related to each other have the same slope or rate of change at all points along their respective lines. For example, consider a function f(x) = 3x^2
