Use interval notation using brackets and parentheses

Suppose that the functions f and g are defined as follows. f (x) = V2x+5 g (x) = 4x-+3x Find fig and f+ g. Then, give their domains using interval notation. ( .8) ( x ) = 1 OVO (0,0) [0,0] Domain of f.g : DUO (0,0] [0,0) OO -OO ( + 8 ) ( x ) = 1 X ? Domain of f+ g
