Question

The graph of a polynomial f(x) is as shown in Fig. 2.21. Write the number of real zeros of f(x).

Answer 1

The graph of a polynomial `f(x)` touches x−axis at two points

The curve y = f(x) crosses or touches the x-axis at three distinct points.

These are the points where f(x) = 0.

Number of real zeros = 3

The polynomial has 3 real zeros because it intersects the x-axis at three points.
