HL 4.1 - Exponential functions
SL 2.9: Exponential functions and their graphs: f(x)=a^x , a>0 ; f(x)=\textrm{e}^x Exponential functions describe many real-life processes: bacteria growth, compound interest in a bank account, and car depreciation, for example. Any process that involves change by a constant factor in a fixed period can be modelled with exponential functions. As such, studying them is an essential part of any mathematical education....
