Question

4. Write the number of zeroes of the polynomial y = f(x) whose graph is
given in the figure.
​

Answer 1

there are 3 zero, since line intersecting x axis at three points

Step-by-step explanation:

hope this helps

Answer 2

We find that, y = f(x) cuts the x-axis at 3 points therefore, the number of zeroes of f(x) is 3. Hence, verified. Hence verified. ∴ 2, 1, 1 are the zeroes of x3 - 4x2 + 5x - 2.
