Answer:
F
Explanation:
"having two x-intercepts" means that the curve must intercept the x-axis twice.
that immediately eliminates A, B, C, D.
A and B have only one "touch" with the x-axis.
C and D have 0 intersections with the x-axis.
so, is E or F correct ?
that is decided by the fact that a < 0. that means that the parabola opens downwards.
and so, F is correct.
