Answer 2

Given:

The graph of y = f(x)  

To find:

How many zeroes are there of f(x)?

Solution:

From given, we have a graph of y = f(x)

Consider the attached figure while going through the following steps.

The equation of the graph is, y = f(x)

This equation represents that, the graph is a function of the x-axis.

Thus, we have to concentrate on the values of x to get the zeros of the equation, f(x).

As, the graph cuts (or passes) the x-axis 2 times, thus, there are 2 zeros of the equation, y = f(x).
