Solution:
The zero’s of the polynomial are the points  where the graph meet x axis in the Cartesian plane. If the graph does not meet x axis ,then the polynomial does not have any zero’s.
  1.  Since it does not intersect x-axis ,it does not have any zero’s
  2. Since it intersect x-axis once ,it has one zero
  3. Since it intersect the x-axis thrice,it has three zero’s
  4. Since it intersect the x-axis two,it has two zero’s
  5. Since it intersect the x-axis four times,it has four zero’s
  6. Since it intersect the x-axis thrice,it has three zero’s
