The graph open upward yes because 6>0 positive number
The graph is the same as the graph of f(x)=6x^2+12x-3 yes because you can just expand the binomial 6(x+1)^2 you get 6x^2+12x+6 with -9 outside
it becomes 6x^2+12x-3
The vertex is (1,-9) no the vertex is (-1,-9)
the graph is shifted up 9 unites no it is shifted down 9 units
the graph is steep yes the large a is the steep the parabola if 0<a<1 then the parabola is less steep
