Logarithmic and exponential functions
Logarithmic and exponential functions
Understanding Exponential and Logarithmic Functions
- Become proficient with the concept of exponential functions, understanding its base, exponent, and how changing each affects the function’s behaviour.
- Identify and utilise the properties of exponential functions to simplify expressions and to solve equations.
- Plot and interpret the graphs of exponential functions. Recognise the exponential growth and decay.
Logarithmic Functions
- Comprehend the principles of logarithmic functions, focusing on the relationship between a logarithm, its base, and the number.
- Apply the three main properties of logarithms, which include product, quotient, and power, to simplify logarithmic expressions.
- Exploit the inverse relationship between exponential and logarithmic functions to transform equations.
- Plot and interpret the graphs of logarithmic functions. Notice the behaviour of the graphs and the asymptotes.
Solving Exponential and Logarithmic Equations
- Learn to solve exponential equations, both graphically and algebraically.
- Develop skills to solve logarithmic equations, using techniques such as making the bases identical, changing the base, or using the one-to-one property of logarithm.
- Understand the process to solve equations involving both exponential and logarithmic functions.
Real-World Applications
- Apply your knowledge of exponential and logarithmic functions to solve real-world problems, such as those involving population growth, radioactive decay, and compounding interest.
- Comprehend the concept of continuous compounding and its link with the natural logarithm, e.
- Utilise the concept of the half-life of a substance in modelling its decay.
