Exponential Modelling

Summary

given a set of data points from an experiment or survey, it is possible to find a mathematical function which "fits" or models the data.

exponential and power functions often model real life situations.

logarithms are used to transform the exponential function into a straight line graph from which the values of constants can be found.

Key Skills

  • decide whether an exponential model is suitable for given data
  • find the value of the constants in the exponential model used for a set of data
  • use the exponential function found to predict other values

Vocabulary

exponential function, logarithms, gradient, y-intercept
