# What are the rational zeros of a polynomial function?

##### 1 Answer

See explanation...

#### Explanation:

A polynomial in a variable

So some examples of typical polynomials might be:

#x^2+3x-4#

#3x^3-5/2x^2+7#

A polynomial function is a function wholse values are defined by a polynomial. For example:

#f(x) = x^2+3x-4#

#g(x) = 3x^3-5/2x^2+7#

A zero of a polynomial

For example,

A rational zero is a zero that is also a rational number, that is, it is expressible in the form

For example:

#h(x) = 2x^2+x-1#

has two rational zeros,

Note that any integer is a rational number since it can be expressed as a fraction with denominator
