Solution:

(i) Graph y = p(x) does not intersect the x-axis.
Hence, p(x) has no zero of p(x).

(ii) Graph y = p(x) intersects the x-axis at only one point.
Hence, there is only one real zero of p(x).

(iii) Graph y = p(x) intersects the x-axis at three points.
Hence, there are three real zeroes of p(x).

(iv) Graph y = p(x) intersects the x-axis at two points.
Hence, there are two real zeroes of p(x).

(v) Graph y = p(x) intersects the x-axis at four points.
Hence, there are four real zeroes of p(x).

(vi) Graph y = p(x) intersects the x-axis at three points.
Hence, there are three real zeroes of p(x).
