The mathematical concept of a function shows clearly how one quantity completely determines the value of another quantity.

Usually, numerical functions are considered that put one number on the other.

A zero of a function is usually called the value of the argument at which the function goes to zero.

Instructions

1

In order to find the zeros of a function, it is necessary to equate its right-hand side to zero and solve the resulting equation. Suppose you are given a function f (x) = x-5.

2

To find the zeros of this function, we take and equate its right-hand side to zero: x-5 = 0.

3

Solving this equation, we get that x = 5 and this value of the argument and will be the zero of the function. That is, with the value of argument 5, the function f (x) vanishes.
