Given the standard equation for a parabola opening up or down which way does a parabola open when the coefficient of the x2term a is negative Up or down?
down
What do you call the graph of a quadratic equation?
A PARABOLA. If the coefficient of 'x^(2)' is positive (+), then the parabola is 'bowl' shaped. If the coefficient os 'x^(2)' is negative (-), then the parabola is 'umbrella' shaped. This shape of parabola has the general eq'n of y = (+/-) ax^(2( + bx + c For a parabola lying on its side ; open side to the right, then the general eq'n is ; y^(2) = 4ax.

When does a parabola open down?
No, a parabola is the whole curve, not just a part of it.
Given the standard equation for a parabola opening up or down which way does a parabola open when the coefficient of the x2 term a is positiveUp or down?
In that case it opens upwards.
