Answer
Focus: $( 1,-\frac{11}{6})$ and vertex : $(1,-2)$
Work Step by Step
As we given that $3x^2-6x-2y=1$ or $3(x^2-2x)=2y$
Thus, $3(x-1)^2-4=2y$
Also, $y=\frac{3}{2}(x-1)^2-2$, which shows an equation of an upward parabola with $(h,k+p)=(1,-2+1/6)=( 1,-\frac{11}{6})$
Hence, Focus: $( 1,-\frac{11}{6})$ and vertex : $(1,-2)$
