PlotExponential function is defined everywhere on real axis. Its plot is depicted below — fig. 1. Fig. 1. Plot of the exponential function y = ex.Function codomain is positive half of the real axis: (0, +∞). 3. IdentitiesBy definition: elnx ≡ xNegative argument: e−x = 1 /exSum and difference of arguments: ex + y = ex eyex − y = ex/ey Product of arguments: exy = (ex)yBase change: ax = ex lna4. SupportExponential function exp of the real argument is supported by free version of the Librow calculator. Exponential function exp of the complex argument is supported by professional version of the Librow calculator. 5. How to useTo calculate exponent of the number:
To calculate exponent of the current result:
