Given f(x)=4x^2-2x-6 and g(x)=2x-3, find the domain of (f-g)(x) and the domain of (f/g)(x). Thanks!Answer by oscargut(891)   (Show Source): You can put this solution on YOUR website!The domain of f(x) are x values where f(x) exists f(x)=4x^2-2x-6 and g(x)=2x-3 when you have polynomial functions then domain is R (real numbers) then domain of f,g and f-g is R when you have f/g the problem is when g(x)=0 because you can not divide by 0 so the domain are all real numbers where g(x) is not 0 then domain of (f/g)(x) is Real numbers but not 3/2 (R-{3/2})
