Describe the transformations required to obtain the graph of the given function from a basic trigonometric graph. y= - cot x +8 . . . Select the correct choice below and fill in the answer boxes to complete your choice. (Simplify your answer. Type an exact answer, using it as needed. Use integers or fractions for any numbers in the expression.) O A. It is the graph of y= cot x after a reflection across the x-axis and a vertical translation of unit(s). O B. It is the graph of y = cot x after a vertical stretch by a factor of , a reflection across the x-axis, and a horizontal translation of unit (s). O C. It is the graph of y = cot x after a horizontal stretch by a factor of and a vertical translation of unit(s). O D. It is the graph of y = cot x after a horizontal stretch by a factor of , a reflection across the x-axis, and a vertical translation of unit(s)
