#### Answer

It is a polynomial $f(x) =\dfrac{-x}{2}+3$ of degree: $1$
Leading term: $\dfrac{-1}{2}x$
Constant: $3$

#### Work Step by Step

We re-arrange the given function as follows:
$f(x)=\dfrac{-x}{2}+3$
A polynomial can be defined as a function containing only terms where $x$ is raised to a positive, integer power or constant. We can see from the given function that it is a polynomial. The degree is equal to the power of the term with the highest power, so the degree is $1$. Also, the constant value is $3$.
The term with the highest degree is always known as the leading term; that is, $4x^4$.
So, it is a polynomial $f(x) =\dfrac{-x}{2}+3$ of degree: $1$
Leading term: $\dfrac{-1}{2}x$
Constant: $3$
