Does anyone know how to work this out?

which  best  describes the transformation from the graph of  f(x) =  x2  to the graph of  f(x) = (x  – 3)2  – 1?   left 3 units, down 1 unitleft 3 units, up 1 unitright 3 units, down 1 unit  right 3 units, up 1 unit

Solve 3x-18=2y and 5x-6y=6 by elimination show work

Y=(x+3)(x-4)(x+1)^2 sulutions? multiplicity?
