The functions f and g are defined by f(x)=(16-x²)² and g(x)=(x²-1)² respectively. Suppose the symbols Df and Dg denote the domains of f and g respectively. Determine and simplify the equation that defines a)f+g and give the set Df+g b)f-g and give the set Df-g c)f.g and give the set Df.g d)f/g and give the set D f/g.
