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
(-1,9) because Y is always the second number and -3*-1=3 so 9=3+6 basically :)
No it doesn't. 2*0.5 + 5*0 = 1, not 19
