Answer
monomial, x, -4, 2.
Work Step by Step
Monomials have the form:
$$ax^k$$
where $a$ is a constant coefficient, $x$ is a variable, and $k$ is a non-negative integer (the degree).
The expression $-4x^2$ is a monomial because it matches the form above. We can see that:
- The variable is $x$.
- The coefficient is -4.
- The degree is 2.
