Opening of parabola formula
WebIf you are using an equation for a parabola in the form of y=ax^2+bx+c then the sign of a ( the coefficient of the squared term ) will determine if it opens up or down. WebDoes the parabola open upwards or downwards? Show Answer. The vertex is (3,4) and it opens upwards since a is positive( it is 2), it opens upwards. Problem 5.2.
