Solve

Function Solve within Real To Real Function with keys 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(x₀) = y
Currently only one-dimensional solver is supported, which means the caller function ƒ is constrained to map one real variable to one real variable.
