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 of**m**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.Note

Before looking for the value of the function at the point - make sure it is in the domain of the function.

Useful advice

Similarly, you can find the value of a function of several arguments. The difference is that instead of a single number, you will need to substitute a few - the number of function arguments.
