The functions f and g are both defined on the domain of all real numbers with f(x)= x*2 and g(x)= 3x+5

write equations for the functions f•g and g•f

h(x)= (1/3x+5)*2 what are the domain and range of h?

find an equation for a function k so that h is equal to one of these compositions f•k k•f g•k k•g or f•k•g answer asap
