Answer:

Step-by-step explanation:
Given that f(x) is a polynomial function.
This implies that f(x) has x terms of positive integral degrees and also rational coefficients only.
Since an irrational root is given a root of f(x), we find that its conjugate also should be a root of f(x)
i.e. If
is a root, then
is also a root.
(Because this only when multiplied will make coefficients rational)
So the factors of f(x) should be atleast

There can be other factors also but this is compulsory
Answer:

Step-by-step explanation:
Answer:
Factor: Something which is multiplied by something else. A factor can be a number, variable, term, or a longer expression. For example, the expression 7x(y+3) has three factors: 7 , x , and (y+3) .
Answer:
The relation is 
Step-by-step explanation:
x and y are directly proportional:
This means that the equation is given by:

In which a is the multiplier that relates these two variables.
x= -4, y =6
We use this to find a. So




So
The relation is
