9 (a) The function f is defined, for all real x, by f(x)=13-4x-2x^2 .(i) Write f(x) in the form a+b(x+c)^2 , where a, b and c are constants.[3] (ii) Hence write down the range o f f.田(b) The function g is defined, for x≥1, by g(x)=√(x^2+2...
ParserNG comes with a FunctionManager class that allows users persist store functions for the duration of the session(JVM run). You may create and store a function directly by doing: FunctionManager.add("f(x,y) = x-x/y"); And then retrieve and use the function like this: ...
