Tutorial Exercise Identify the open intervals on which the function is increasing or decreasing. g(x) = x2 - 2x - 224 Step 1 To determine the intervals on which the function is Increasing or decreasing, first find the critical numbers of the given function. Determine g'(x). g(x) = x2 - 2x - 224 g(x) = Submil Skip (you cannot come back)
