Use interval notation using brackets and parentheses

Suppose that the functions f and g are defined as follows. f (x ) = Vx-2 g (x) = 5x+4 Find f-g and fig. Then, give their domains using interval notation. ( - 8 ) ( x ) = 1 OVO (0,0) [0,0] Domain of f - 8 : OVO (0,0] [0,0) - 00 ( . 8 ) ( x ) = 0 X 5 ? Domain of f.8
