    It seems like base e comes along with F.LE.4 which is an Algebra 2 standard. I suspect base e is delayed from Algebra I to be introduced with logarithms, but I see in some software packages it is mixed in with exponential functions in general. Am I correct that base e was intended to be delayed?

    Well, remember that course placement is not included in the standards; I guess you are probably looking at Appendix A, correct? I could imagine introducing exponential functions with base e quite early as a standard function in science and finance, and delaying the explanation until later.
