Suppose x is a collection of all binary representations of all real numbers. if f: x→r(where r is a collection of all real numbers) is function defined by f(x) is a decimal representation of x. (i) find f(10011012) (ii) does f-1 (x) exist? explain in detail. if f-1 (x) exists then define it and find f-1 (2043.2) 2. if f(x)=5 and g(x)=2x+1 then find ∘ and ∘ .
