WebThe standard form of parabola equation is expressed as follows: f (x) = y= ax2 + bx + c The orientation of the parabola graph is determined using the “a” value. If the value of a is greater than 0 (a>0), then the parabola graph is oriented towards the upward direction. If the value of a is less than 0 (a<0), then the parabola graph opens downwards. WebIf the parabola opens downward like this, the vertex is the topmost point right like that. It's the maximum point. And the axis of symmetry is the line that you could reflect the parabola around, and it's symmetric. So that's the axis of symmetry. That is a reflection of the left-hand side along that axis of symmetry. how to declare mutual funds in tax
