# What is a monomial function?

Jul 24, 2014

A monomial is a mathematical expression which is made up of only one term.

It cannot contain any addition or subtraction signs or a negative exponent.

These are monomials:

• ${a}^{2}$
• $6 {a}^{2} {b}^{4}$
• $- 6 {x}^{2} {y}^{4}$

These are not monomials: (they are polynomials)

• ${b}^{3} + c$
• $5 {x}^{-} 3$
• $5 {x}^{3} - {x}^{4}$
