Suppose the graph of the parent function y=cot(x) is vertically compressed to produce the graph of the function y=acot , but there are no reflections. Which describes the value of a?

21/2 or 5/2

Answercounterclockwise rotation about the origin by 180 degrees followed by reflection about the y-axisexplanationthe given figure has verticesrecall that for counterclockwise rotation about the origin, when we rotate figure pqrs counterclockwise through an angle of 180° about the origin, the coordinates will becomenext, we reflect in the y-axis by negating the x-coordinates of the resulting figure to obtain,therefore the correct answer is c
