Answer:

<h3>The given set of polynomials f(x) and g(x) are closed under subtraction.</h3>

Step-by-step explanation:

Given that the functions f ad g are defined by

$f(x)=7x^3-3x^2-x+14$ and $g(x)=2x^3+2x+5$ respectively.

<h3>To show that the set of polynomials is closed under subtraction :</h3>

Now subtract the given polynomials

$f(x)-g(x)=(f-g)(x)$

$=7x^3-3x^2-x+14-(2x^3+2x+5)$

$=7x^3-3x^2-x+14-2x^3-2x-5$

$=5x^3-3x^2-3x+9$

∴ $f(x)-g(x)=5x^3-3x^2-3x+9$

When subtracting the polynomials the variables and their exponents remains same only variation in their coefficients.

<h3>Hence the given polynomials f(x) and g(x) are closed under subtraction.</h3>

∴ $f(x)-g(x)=5x^3-3x^2-3x+9$ are closed under subtraction,

Hence showed.
