Find the number of zeros of the following polynomial represented by th

1.	Find the number of zeros of the following polynomial represented by their graphs.
Answer» (i) The curve cuts the x-axis at two points. ∴ The equation has 2 zeros. (ii) Since the curve cuts the x-axis at 3 different points. The number of zeros of the given curve is three. (iii) Since the curve doesn’t cut the x axis. The number of zeros of the given curve is zero. (iv) The curve cut the x-axis at one point. ∴ The equation has one zero. (v) The curve cut the x axis at one point. ∴ The equation has one zero.

Find the number of zeros of the following polynomial represented by their graphs.

Answer»

(i) The curve cuts the x-axis at two points. ∴ The equation has 2 zeros.

(ii) Since the curve cuts the x-axis at 3 different points. The number of zeros of the given curve is three.

(iii) Since the curve doesn’t cut the x axis. The number of zeros of the given curve is zero.

(iv) The curve cut the x-axis at one point. ∴ The equation has one zero.

(v) The curve cut the x axis at one point. ∴ The equation has one zero.
