Question 1153849


In particular, for an expression to be a polynomial term, it must contain
- {{{no }}}square roots of variables, 
-{{{no }}} fractional or negative powers on the variables, and
- {{{no }}} variables in the denominators of any fractions. 



1. {{{3x^2 - 5x + 2}}}

D This is a polynomial because it is the sum of monomials with whole-number exponents.


2. {{{1/x^4 + 5x^2 - 4x + 1 }}} 

B This is not a polynomial because {{{x^4}}} is in the denominator.


3. {{{4x^-3 + 3x^2 + 2x + 1}}}

F This is not a polynomial because x is raised to a negative power in the first term.


4.{{{ 7x^5 + 3x^4 - 2x^2 + 7}}}

E This is a polynomial because it is the sum of monomials with whole-number exponents.


5. {{{sqrt(x) + 12}}}

A This is not a polynomial because the variable is underneath a square root sign.
