Question -10 -8 Sorry, that's incorrect. Try again? (-∞, -2) U (3,00) -6 Y 10- 8 6- -6- +8- 10- 4 6 8 The graph of f(x) is shown in the figure. Where is f'(x) < 0? Give your answer using interval notation. If f'(x) < 0 from 5 to -3, enter (-5, -3). If f'(x) < 0 from -5 to -3 then again at all points after 6, enter (-5, -3) U (6, ∞o). The U symbol can be found by changing "basic" to "sets" in t drop-down menu. + x 10
