Why might it be useful to know the linear factors of a polynomial function?

It is useful to know the linear factors of a polynomial because they give you the zeros of the polynomial. If (x-c) is one of the linear factors of a polynomial, then p(c)=0.
Here the notation p(x) is used to denoted a polynomial function at p(c) means the value of that function when evaluated at c.
Conversely, if d is a zero of the polynomial, then (x-d) is a factor.

In SQL what is the function of the union operator?
In SQL, the function of the union operator is to combine the result of two or more select-statements. The union operator is a very useful tool when coding SQL.
Why linear programming use in Economics?
Economics is essentially about the allocation the least quantities of scarce resources to maximise utility. Resources could be money - so minimise cost - while utility may be measured by profits. If the production options can be modelled by linear functions - as they often are - then LP is a very useful tool. It is also easily programmed into computers.
How do you use a vertical line test to determine if a graph represents a function?
A vertical test line is useful because, by definition, a function has one and only one result value for each input value. If you can find a vertical line that intersects the curve of the line, then it is not a function. A simple example is a circle.
When is it useful to know about factors and multiples?
It is always useful to know about factors and multiples.
When is it useful to use factors and multiples?
Factors are useful when you're trying to reduce fractions. Multiples are useful when you're trying to find a least common denominator.

What are the applications of linear transformations?
Linear transformations can be very important in graphics. Also, linear transformations come up whenever you need to solve systems of linear equations, which arise quite often. Finally, they can be useful in further areas of mathematics such as topology.

No. It is a useful function of the body.
What would the output be if the input was 10.20 on the function table?
It will be f(10.20), which is determined by the function f. Since you have not bothered to share what the function f is, I cannot provide a more useful answer.It will be f(10.20), which is determined by the function f.
