Which function has a vertex at (2, -9)? O f(x) = -(x - 3)2
O f(x) = (x + 8)2
O f(x) = (x - 5)(x + 1)
O f(x) = -(x - 1)(x - 5)

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
