Ok look at the equation it says that f(x) is g(x) squared. F(x) is equal to x^2 so to get g(x) you would have to redo the equation of f(x)=[g(x)]^2. Now the only problem is that g(x) is squared and we have g(x) so we need the squareroot it to remove the square and we have to squareroot f(x) as well. So now the equation is g(x)=[tex] \sqrt{f(x)} [/tex] Now just plug in the f(x) term and solve for g(x)=x
