Homework Answers
(a) We can notice that the graph of (a) has two distinct x-intercepts. This implies that in this case discriminant is positive.
.
(b) In this case, we can notice that the graph of (b) has one x-intercept of multiplicity 2, which implies that in this case discriminant is zero.
.
(c) In this case, we can notice that the graph has no x-intercepts which implies that in this case the discriminant is negative.
