Solve

Function Solve within Timed Real To Real Function with keys Timed Real To Real Function Solve keysreturns the value x₀ that the independent variable x must have in order for the caller function ƒ to evaluate to a given target number y
In other words, it solves for the x₀ that satisfies:
ƒ(d ; x₀) = y
where d is a specified date that is passed as the first input variable to the function ƒ.
Currently only one-dimensional solver is supported, which means the caller function ƒ is constrained to map one date followed by one real variable to one real variable.
