Which of the following is a polynomial a. x^2+2 b.(x^8-2)/(x^-2+3) c. 7x^7-2x^-4+3 d. x^x-1

 A. x²+2   - a  polynomial
B.(x⁸-2)/(x⁻²+3)  rational function
C. 7x⁷-2x⁻⁴+3 (It has negative value of exponent, so it cannot be a polynomial.)
D.x^x-1 (x is an exponent it cannot be a polynomial)

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
