In order to find the x-intercepts of this parabola we must set and then solve the quadratic equation using GDC.
For example, the commands for Casio FX-9860G II to solve a quadratic equation are:
MENU>EQUA>F2(Polynomial)>Degree (2)>insert the coefficients and get two real roots,
. So the points of x-intercepts are .
Therefore the correct answer is (B).
Hope these help!!:)
