__Exercise – 2.1__

**1. The graphs of y=p(x) are given in following
figure 2.10, for some polynomials p(x), Find the number of zeroes of p(x), in
each case. **

figure 2.10 |

solution:

(i) The number of zeroes is 0,
because the graph does not intersect the x-axis at any point.

(ii) The number of zeroes is 1,
because the graph intersects the x-axis at a point.

(iii) The number of zeroes is 3,
because the graph intersects the x-axis at three points.

(iv) The number of zeroes is 2,
because the graph intersects the x-axis at two points.

(v) The
number of zeroes is 4, because
the graph intersects the x-axis at four points.

(vi) The
number of zeroes is 3, because the graph intersects the
x-axis at three points.
