The value of (f - g)(x) is -x² + 3x + 7.
<h3>What is Function?</h3>
The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input x.
Here, the given functions are;
f(x) = 3x + 1
g(x) = x² - 6
Now,
(f - g)(x) = f(x) - g(x)
= (3x + 1) - (x² - 6)
= 3x + 1 - x² + 6
(f - g)(x) = -x² + 3x + 7
Thus, the value of (f - g)(x) is -x² + 3x + 7.

Answer:
All of them are polynomial functions
Step-by-step explanation:
Remember that a polynomial function of x is a function whose value f(x) is always equal to
for a fixed n≥0 (the degree of f) and fixed coefficients 
For example,
is a polynomial function, but
is not because
is not a nonnegative power of x. Another example of a non-polynomial function is
.
f(x)=4⋅11x is polynomial with degree 1 and
. For the same reasons, f(x)=3⋅18x and f(x)=10⋅17x are polynomial functions.
f(x)=−4x³−4x²+5x+1 is a polynomial function of degree 3 with
. and f(x)=−2x−1 is a polynomial function of degree 1 and coefficients
.
