Variation of a Function - Examples, Exercises and Solutions

The variation of a function means the rate at which a certain function changes. The rate of variation of a function is also called the slope.

According to the mathematical definition, the slope represents the change of the function (Y) (Y) by increasing the value of X X by 1 1 .

  • If the function's graph is represented by a straight line, it means that the rate of variation of the function is constant
  • However, if the graph is not represented by a straight line, this implies that the rate of variation of the function is not constant
