How to find the value of the function

The notion of function in mathematics understand the relationship between the elements of sets. More precisely, it is "law" by which each element of one set (called the domain) corresponds to an element of another set (called the range).

1. The value function is a realm of values which a function can take. For example, the values of the function f(x)=|x| from 0 to infinity. To find the value of the function at a particular point, you need to substitute the argument of a function to its numeric equivalent, the resulting number will be the value ofm functions. Let given the function f(x)=|x| - 10 + 4x. Find the value of the function at the point x=-2. Substitute instead of x the number -2: f(-2)=|-2| - 10 + 4*(-2) = 2 - 10 - 8 = -16. That is, the value of the function at the point -2 -16.
