What you need to know
Check yourself against these “I can” statements.
- I can sketch exponential graphs such as y = a^(x) and y = e^(x), and their transformations
- I can explain why the derivative of e^(kx) is ke^(kx) and why that matters
- I can use exponential models and interpret them
- I can switch between index form and log form and use the laws of logs
- I can solve equations such as a^(x) = b and use the natural log, ln
- I can use logs to turn a non-linear model into a straight line and estimate its constants
