Answer:
positive
Step-by-step explanation:
the discriminant of the function is postive.
because from the graph we notice that it has 2 intercepts on x-axis, which means the function has 2 real solution when y=0
that implies the discriminant is positive.

if
we have 2 distinct real solution
if
we have no real solution but 2 complex solutions
if
we have 2 identical real solution
