Express the following function, F(x), as a composition of two functions, f andg. f(g(x)).F(x)=√√3x-4Part 1: Find g(x) by identifying the function you are taking the square root of.Part II: Find f(x) by identifying what you are doing to the function you found inPart I. What function is f(x)? Part III: Verify thatf(g(x)) = F(x)f(g(x))=√√3x-4
