The equation f(x) = 4x4 + 4x2 + 9x – 2 can have at most four distinct real roots. true or false

True.
Basically, the # of solutions of an algebraic equation equals the value of the highest exponent, which in this case is 4.

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
