Answer:
5th degree polynomial
Step-by-step explanation:
We have been given the polynomial
We know that the highest exponent of a polynomial is called the degree of the polynomial.
The highest degree of the given polynomial is 5. Hence, from the above written concepts, we can say that the degree of the polynomial os 5.
Thus, the polynomial is 5th degree polynomial.
First option is correct.

Answer:
Domain: x0 or [0,infinity)
Step-by-step explanation:
f(x)= and g(x)=3-x
We are told to multiply the two functions so we multiply:
(fg)(x)=*(3-x)
(fg)(x)=3-x
Now this is a square root function and it can only go to the right because the square roots of numbers less than 0 are imaginary numbers. Therefore the domain must be greater than or equal to 0.
