Find the acceleration. A curve is defined by the parametric equations \begin{equation*} x=3(t^2-3), \ y=t^3-3t\text{.} \end{equation*} \begin{equation*} x=3(t^2-9), \ y=t(t^2-9), \ -\infty \lt t\lt ...

y=2t^2-4t\text{,}\) \(-\infty \lt t\lt \infty\text{.}\) Which of the two graphs below corresponds to the given parametric curve? Find the \(y\)-coordinates of all points where the curve crosses the ...
