For the function, find the points on the graph at which the tangent line is horizontal. If none exist, state that fact. f(x) = 2x - 3x + 5 Select the correct choice below and, if necessary, fill in the answer box within your choice. O A. The point(s) at which the tangent line is horizontal is (are) (Simplify your answer. Type an ordered pair. Use a comma to separate answers as needed.) O B. There are no points on the graph where the tangent line is horizontal. O C. The tangent line is horizontal at all points of the graph.For the function, find the point(s) on the graph at which the tangent line has slope 4. y = - 0 025x + 7x 2 The point(s) is/are (Simplify your answer. Type an ordered pair. Use a comma to separate answers as needed.)Use the quotient rule to find the derivative of the following. 2 - 4x + 3 V= 2 X +4 =
