Use the given pair of functions f(x) = 3 − x , g(x) 2 = √x + 1 to find and simplify the expression (g ◦ f)(x) and state the domain of each using interval notation.

2) Use the given pair of functions f(x) = 3 − x , g(x) 2 = √x + 1 to find and simplify the expression (g ◦ f)(x) and state the domain of each using interval notation. 3) Show that the given function is one-to-one and find its inverse. Check your answers algebraically and graphically.
