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
Which way does a parabola open when the coefficient of its x2term a is positive?
Upwards: it is cup shaped, not cap shaped.
Does the parabola open up or down?
It does both depending if it is positive or negative
Which way does a parabola open when the coefficient of its y2term a is negative?
Nose points right, opens to the left.
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 the parabola concave downward and upward?
If the number in front of the x squared is negative, then the parabola will open upwards. The opposite occurs when the number is positive.
What does changing the value of a from a negative number to a positive number cause the parabola to do?
open upward
