Answer 1

Answer:

Sol. (i) The given graph is parallel to x-axis. It does not intersect the x-axis.

• It has no zeroes.

(ii) The given graph intersects the x-axis at one point only.

• It has one zero.

(iii) The given graph intersects the x-axis at three points.

• It has three zeroes.

(iv) The given graph intersects the x-axis at two points.

• It has two zeroes.

(v) The given graph intersects the x-axis at four points.

• It has four zeroes.

(vi) The given graph meets the x-axis at three points.

• It has three zeroes.
