Okay, so y = -3x^2 +2x -1 is represented in the first attached image.
Notice it's steep angle.
The graph of answer choice "D" angles downward, so that can't be the right answer.
The graph of answer choice "C" is angled upward, but at a vey wide angle
The graph of answer choice "B" is angled downward once again.
That leaves us with graph A [picture of graph included], which opens upward and appears narrower.
Your best answer choice is A
Hope that helps!
