  • Waiting for answer What is the vertex and direction of this parabola ##y=-3(x+2...

    A parabola in the form: ##y = a(x - h)^2+k## will open up if a 0, and down if a 0. Since a = -3 in your example, the parabola will open down and have a maximum at the vertex. In the form ##y = a(x - h)^2+k##, (h,k) is the vertex. In your example, then, (-2,3) is the vertex. The maximum val...
