 ExponentialFunction

 Calling Sequence ExponentialFunction(f) ExponentialFunction(asymval, pt1, pt2)

Parameters

 f - exponential function in a single variable. asymval - y-value for horizontal asymptote pt1, pt2 - a GridPoint object or rtable/list representing a point on the function

Options

 • domain : a RealRange expression specifying the region over which the function is defined
 • variable : name used in generated expression if the second calling sequence is used

Description

 • The ExponentialFunction constructor generates and returns an object representing an exponential function.
 • The first calling sequence requires an exponential function in one variable to be provided.
 • The second calling sequence requires the value for the horizontal asymptote and two points on the curve to be provided.
