Initials: (3) 6. Given the functions f (x) = x+3 and g(x) =- , what is the simplified form of (s . 8) ( x) ? (3) 7. If f(x) =-3Vx-1 and g(x) = Vx+5, what is the simplified combined function h (x ) =(x), g(x) (5) 8. Given the functions f (x) =x and g(x) =3, sketch the graph of the combined function h(x) = f(x) -8(x)
