polynomial, $n=1$. $f(x)=-\frac{1}{2}x+3$, $-\frac{1}{2}x$, $3$.

Step 1. Given $f(x)=3-\frac{1}{2}x$, we can determine it is a polynomial function. Step 2. We can identify the degree as $n=1$. Step 3. In standard form $f(x)=-\frac{1}{2}x+3$. We can identify the leading term as $-\frac{1}{2}x$ and the constant term as $3$.
