Why is it not surjective? The solution says: not surjective, because the Value 0 ∈ R≥0 has no Urbild (inverse image / preimage?). But e^0 = 1 which is in ∈ R≥0.
Why is X not surjective?
You have not specified the domain and codomain of the your function. In fact, it is onto when you consider it as a function from R to [0,∞). However, it is not onto when considered as a function from R to R as there does not exist a pre-image for any x<0.
Why is exponential function not surjective?
The function g : R → R defined by g(x) = x2 is not surjective, since there is no real number x such that x2 = −1. ... Its inverse, the exponential function, if defined with the set of real numbers as the domain, is not surjective (as its range is the set of positive real numbers).
