Describe the transformation required to obtain the graph of the given function from the basic trigonometric graph. y=csc (x) - 9a.Vertical translation up 9 unitsc.Vertical stretch by a factor of 9b.Horizontal translation to the right 9 unitsd.Vertical translation down 9 units

Answer:Option D is correct .i.e., Vertical translation down 9 unitsStep-by-step explanation: Given Function is y = cosec x - 9Here basic function or parent function is y = cosec x1. When constant ' a ' is added to to parent function or basic function then the function is translated vertically upward by a units.2.  When constant ' a ' is subtracted from parent function or basic function then the function is translated vertically downward by a units.Therefore, Option D is correct .i.e., Vertical translation down 9 units
