#### Answer

The answers are:
\begin{align}
x^4: &\color{red}{\text{Coefficient is 1 and Degree is 4}}\\
-x^3: &\color{red}{\text{Coefficient is -1 and Degree is 3}}\\
4x: &\color{red}{\text{Coefficient is 4 and Degree is 1}}\\
-3: &\color{red}{\text{Coefficient is -3 and Degree is 0}}
\end{align}

#### Work Step by Step

To determine the coefficient of a term, identify the part of the term which is the constant factor (usually a number).
To determine the degree of a monomial, identify the number of variable factors in the monomial.
\begin{align}
x^4: &\color{red}{\text{Coefficient is 1 and Degree is 4}}\\
-x^3: &\color{red}{\text{Coefficient is -1 and Degree is 3}}\\
4x: &\color{red}{\text{Coefficient is 4 and Degree is 1}}\\
-3: &\color{red}{\text{Coefficient is -3 and Degree is 0}}
\end{align}
