To determine

The definition of zeros of the function.

Explanation of Solution

The x − intercepts of the graph of the function are called zeroes of the function.

For example:

Let a quadratic function is $y=x^2-4$

The zeroes of the function will be:

  $\begin{array}{l}{x}^2-4=0\\ x^2=4\\ x=\sqrt{4}\\ x=\pm 2\end{array}$

Hence, the zeroes of the function will be $\pm 2$ .
