The exponential function is a mathematical function denoted by () = ⁡ or (where the argument x is written as an exponent).Unless otherwise specified, the term generally refers to the positive-valued function of a real variable, although it can be extended to the complex numbers or generalized to other mathematical objects like matrices or Lie algebras.

Sep 20, 2015 · Well, f(x) = cosh(a ⋅ x) f ( x) = cosh ( a ⋅ x) for any constant a a seems to match the equation, so you may have hard time proving that f(x) ≡ 1 f ( x) ≡ 1. As to whether or not this solution (or rather, a family thereof) is unique, I expect it to be so if we require continuity, but that's another story. Share.

The question is probably hoping you'll write f ′ ( y) = f ′ ( 0) f ( y) which follows from the functional equation. However, the question is entirely wrong since, as you note, f ′ ( 0) = 3 implies f ( 5) = e 15 and could well claim f ′ ( 5) = 3 e 15. This also follows from the givens (as does any other answer). – Milo Brandt.1 comment ( 15 votes) Upvote Flag Maureen Hamilton 12 years ago If y=2x+1 is the original function, why is (y-1)/2=x considered the inverse?
