Find the points on the curve given below, where the tangent is horizontal. (round the answers to three decimal places.) y = 7 x 3 + 6 x 2 - 8 x + 7

The answer is y = -23 im in middle school

What the heck don’t understand

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
