Two polynomials are graphed on the same axes.
• P(x) is linear and intersects the x–axis at (−3,0).
• Q(x) is quadratic and intersects the x–axis at (1,0) and (5,0).
Which statement about their real zeros is correct?
a) Neither P(x) nor Q(x) has any real zeros.
b) P(x) has more real zeros than Q(x).
c) Q(x) has more real zeros than P(x).
d) P(x) has two real zeros, whereas Q(x) has only one real zero.
