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.
[tex]\Delta = \sqrt{b^2-4ac}[/tex]
if [tex]\Delta > 0[/tex] we have 2 distinct real solution
if [tex]\Delta <0[/tex] we have no real solution but 2 complex solutions
if [tex]\Delta = 0[/tex] we have 2 identical real solution
