SL 2.9—Exponential and logarithmic functions Topic Practice
Practise using exponential and logarithmic functions to evaluate values, solve transformed equations, analyse domains and make model predictions.
How this is tested
- calculate values such as f(8) or f(1/4) by substituting into log expressions and simplifying powers
- solve equations by rewriting terms such as 9^x as (3^x)^2, then interpreting valid logarithmic solutions
- apply exponential models to contexts, using the given formula to predict quantities at specified times
