The graph of a curve CC is given below for certain values of xx. Diagram for question 15 What could be the equation of CC?

Ay=x3ecos⁡3x+ln⁡x2y=x^3e^{\cos3x}+\ln x^2
By=x3esin⁡3x+ln⁡x2y=x^3e^{\sin3x}+\ln x^2
Cy=x3ecos⁡4x+ln⁡x2y=x^3e^{\cos4x}+\ln x^2
Dy=x3esin⁡4x+ln⁡x2y=x^3e^{\sin4x}+\ln x^2
Ey=x3ecos⁡3x−ln⁡x2y=x^3e^{\cos3x}-\ln x^2
Fy=x3esin⁡3x−ln⁡x2y=x^3e^{\sin3x}-\ln x^2
Gy=x3ecos⁡4x−ln⁡x2y=x^3e^{\cos4x}-\ln x^2
Hy=x3esin⁡4x−ln⁡x2y=x^3e^{\sin4x}-\ln x^2
