DYLAN WALLACE 1/21 Question 1 of 10, Step 2 of 3 Correct Intervals of Increasing or Decreasing Step 2 of 3 : The derivative of a function has already been found and factored to bef (x) = (x - 7) (x + 5). Use the critical values obtained in Step 1 to create intervals on a number line to test. Determine which intervals the original function (which we are not given and don't need) is increasing and which intervals it is decreasing, if any. Answer Keypad Keyboard Shortcuts O Increasing on the interval(s): ( - co, -5) U (7, co) ; Decreasing on the interval(s): (-5, 7) O Increasing on the interval(s): (-5, 7); Decreasing on the interval(s): ( - co, -5) U (7, co) Increasing on the interval(s) ( - co, -7) U (-7, 5); Decreasing on the interval(s): (5, co) Increasing on the interval(s): (-5, 7) U (7, co); Decreasing on the interval(s): ( - co, -5) U (7, co) None of these. Increasing on the interval(s): (-5, 7) U (7, co); Decreasing on the interval(s): ( - co, -5) Submit Answer 2023 Hawkes Learning
