vertex:$(3,1)$ and defines at opens towards left. and Domain is: $(- \infty, 3]$ and range is: $(-\infty, \infty)$
Since, we have $x=-4(y-1)^2+3$ Standard form of a horizontal parabola is $x=a(y-k)^2+h$ Here, vertex:$(h,k)$ Compare the above equation with the standard form. Thus, we have vertex:$(3,1)$ and defines at opens towards left. and Domain is: $(- \infty, 3]$ and range is: $(-\infty, \infty)$
