1. The problem statement, all variables and given/known data Hi I have an equation as follows: f(x) = (2x-2.3)/(2x-5.29)^2 what i got for the derivative was: f'(x) = (-1.38-4x)/(2x-5.29)^3 2. Relevant equations f(x) = (2x-2.3)/(2x-5.29)^2 f'(x) = (-1.38-4x)/(2x-5.29)^3 3. The attempt at a solution what i got for the critical point is -0.345, but then the question asks when the function is increasing and decreasing, expecting 3 intervals. if there is only one critical point, i can see two intervals but not three. am i missing a critical point here? i have excluded x = 2.645 because it is not a part of the domain.
