Answer:
A function tells a relationship between an input(there can be more than one) and a single output.
Given statement is - the distance Annette traveled was a function of speed and the amount of time she drove.
Here, the word function tells us, that for a given input (speed and time in this case) there is a single output (distance) that Annette drove.
Moreover, we know that distance is the product of speed and time.
or
f(speed,time) = speed x time

Step-by-step explanation:
1 ) Given that
For a non homogeneous part , we assume the particular solution is
2 ) Given that
For a non homogeneous part , we assume the particular solution is
3 ) Given that
y′′ + 4y′ + 20y = −3sin(2x)
For a non homogeneous part −3sin(2x) , we assume the particular solution is
4 ) Given that
y′′ − 2y′ − 15y = 3xcos(2x)
For a non homogeneous part 3xcos(2x) , we assume the particular solution is
We have been given two polynomials
Let us first multiply these polynomials.
Now, we know that polynomials follows closure property of multiplication.
It means that when we multiply two polynomials, the result will be a polynomial.
Since, when we multiplied the given polynomials, we got which is a polynomial.
Therefore, the correct option is
The result is a polynomial.
