Investigate the change in the graph of a sinusoidal function of the form and $$= \sin x$$ or and$$= \cos x$$ when multiplied by a polynomial function. Describe the behavior of the graph of and$$=x^2 \sin x$$ in relation to the graphs of and$$=x^2\ and\ =−x2a$$.
The graph of $$\displaystyle{y}={x}^{{2}}{\sin{{x}}}$$ oscillates between the graphs of $$\displaystyle{y}={x}^{{2}}$$ and $$\displaystyle{y}=-{x}^{{2}}$$.
