  1. i figured out the f^-1(x) is the ln ((-13x-6)/(17x-5)) i just need a and b plz help before 11 pm

  2. For logarithmic expression, the value of u in ln u should be more than 0. So:
    (13x + 6)/(5 - 17x) > 0
    Use the number line to solve this, you'll get the result.
    If my calculations are correct, then: (-6/13,5/17)
