      2.2 Exponential and Logarithmic Functions
    • Exponential and Logarithmic Functions

    • This Teacher Pack will cover the following syllabus content:

      • understand the relationship between logarithms and indices, and use the laws of logarithms (excluding change of base)
      • understand the definition and properties of e^x and ln⁡x, including their relationship as inverse functions and their graphs
      • use logarithms to solve equations and inequalities in which the unknown appears in indices
      • use logarithms to transform a given relationship to linear form, and hence determine unknown constants by considering the gradient and/or intercept.


      This unit of work is just one of several approaches you could take when teaching this topic, and you should aim to adapt the resources to match the ability level of your learners as well as your learner context.
