Find the open intervals on which the function f(x)=x+41−x−−−−−√ is increasing or decreasing. If the function is never increasing or decreasing, enter NA in the associated response area.

Ithink the answer is a

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
