Given function f, find its inverse function, f- (x). f (x) = _15x - 7 x - 2 (Use symbolic notation and fractions where needed.) f- ( x ) = Find the domain and the range of f (x). (Use symbolic notation and fractions where needed. Give your answers as intervals in the form (*, *) . Use the symbol co for infinity, U for combining intervals, and an appropriate type of parenthesis "(", ")", "[" or "]" depending on whether the interval is open or closed.) X E f-( x ) E
