I Given functions f and g, construct the composite functions ( g) (x) and (g ) (x). f(x) = g(x) = X -x--6 Then, determine each composite function's domain using interval notation. (Express numbers in exact form. Use symbolic notation and fractions where needed. For function's domain give your answer as an interval in the form (*, *). Use the symbol for infinity, U for combining intervals, and an appropriate type of parenthesis (",")", "[","]" depending on whether the interval is open or closed. Enter if the interval is empty.) 11 (fog)(x) = domain of (fog)(x): (gof)(x) = domain of (gof)(x):
