Answer:
The given expression can't be expressed in polynomial form. Hence, it is not a polynomial.
Step-by-step explanation:
P(x,n) is a polynomial of nth degree if it is of the form,
P(x,n) =
where n is a finite positive integer and n ∈ N
and ''s are fixed but otherwise arbitrary constants ∀ i = 0(1)n .
Now, the given expression is,
which doesn't fit in the above form. Hence, it is not a polynomial.
The domain of the function f(x) is where the area under the square root (aka the radicand) is positive or zero. We have to write that the radicand is greater than or equal to zero, so
.
