Suppose that the functions f and g are defined as follows: f(x) = √(5x+4) g(x) = 4x²+1 Find f⋅g and f-g. Then, give their domains using interval notation. (f⋅g)(x) = Domain of f⋅g: (f⋅g)(x) = (√(5x+4))(4x²+1) Domain of f⋅g: All real numbers (f-g)(x) = Domain of f-g: (f-g)(x) = (√(5x+4)) - (4x²+1) Domain of f-g: All real numbers Suppose that the functions f and g are defined as follows: f(x) = √(5x+4) g(x) = 4x+1 Find g and -g. Then, give their domains using interval notation. g(x) = 4x+1 Domain of g: All real numbers -g(x) = -(4x+1) Domain of -g: All real numbers Please note that the original text contained several errors, including incorrect equations and missing information.
