4X . Find its inverse. Let f (x) = 3x-1' (Express numbers in exact form. Use symbolic notation and fractions where needed.) f- (x) = 5x - 4 Find the domain and the range of f-1 (x) . Give your answer as an interval in the form (*,*). Use the symbol co for infinity, U for combining intervals, and an appropriate type of parenthesis "(",")", "[","]" depending on whether the interval is open or closed. Enter O if the interval is empty. Express numbers in exact form. Use symbolic notation and fractions where needed.) the domain is x E (-00,00) Incorrect the range is y E (-00,00 ) Incorrect
