Question 1204492
<font color=black size=3>
A single variable polynomial involves terms of the form {{{c*x^d}}} where c is the coefficient and d is the exponent.
The value of d must be a nonnegative whole number {0,1,2,3,...}
{{{c*x^d}}} is considered a monomial. Add or subtract a bunch of monomials to get a polynomial.
An example of a polynomial would be 2x^3 + 7x + 10 and what is shown in <font color=red>choice D</font>.


Negative exponents are not allowed because it leads to dividing over x.
Example: {{{x^(-2) = 1/(x^2)}}}
This rules out choices A and C.


Furthermore, this list of items aren't allowed either<ul><li>square roots</li><li>logs</li><li>variables in the exponent</li><li>trig functions (sine, cosine, etc)</li></ul>This rules out choice B.
