For other bases the pattern is: logₐ (−k) = logₐ (k) + logₐ (e)*π 𝑖. =lim1+and more generallyex =lim1+ n→∞nn→∞n More importantly, this again shows that earises very naturally. We will add 2 to the corresponding consecutive outputs. 6 Exponential And Logarithmic EquationsChapter Questionsexpand_more. In order to get the graph, you just need to specify the parameters A_0 A0 and k k for one or two functions (depending on whether you want to.
