Answer:
2, 4, 5
Explanation:
Assuming you meant 6(x+1)^2-9
1.) no, the vertex is (-1,-9)
2.) this is true. this is because the 6 is positive. if it was negative, it would be concave down
3.) no, you shift it down 9 units
4.) yeah, multiplying it by 6 makes it narrower
5.) yes --> 6(x+1)^2-9= 6(x^2+2x+1)-9= 6x^2+12x+6-9= 6x^2+12x-3
