## College Algebra 7th Edition

a) (f + g)(x) = f(x) + g(x) The domain of (f + g)(x) is the intersection of the domains of f and g b) (fg)(x) = f(x)g(x) The domain of (fg)(x) is the intersection of the domains of f and g c) $(\frac{f}{g})(x) = \frac{f(x)}{g(x)}$ The domain of (fg)(x) is the intersection of the domains of f and g, g(x) cannot be 0
