B) ​ ,

Quizplus · Accepted Answer

The tangent line of a graph is horizontal when the derivative is equal to zero. Using calculus to find the derivative of the given function, we get 11eb651f_cb7f_bd7f_b0a1_f704e43edd81_TB8255_11 and 11eb651f_cb7f_bd80_b0a1_01cbaf9aa026_TB8255_11 as the x-values where the derivative is equal to zero. These correspond to the points on the graph where the tangent line is horizontal. Therefore, the answer is A.
