/FunctionType 2 - Exponential
(Optional) An array of n numbers defining the function result when x = 0.0. Default value: [ 0.0 ].
(Optional) An array of n numbers defining the function result when x = 1.0. Default value: [ 1.0 ].
(Required) The interpolation exponent. Each input value x will return n values, given by yj = C0j + xN × (C1j − C0j ), for 0 ≤ j < n.
