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

numerical functions usually considered that put in line one other numbers.

Zero function, commonly referred to as the value of the argument for which the function vanishes.

instructions

1

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

2

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

3

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