Convert each equation from standard form to vertex form (Please Show Work.) Thanks in advance Due in the morning

1. y=2x^2-12x+21
2. y=-2x^2+4x
3. y=-2x^2-4x+1
4. y=2x^2-16x+36
5. y=2x^2+8x+10

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
