This triangle is obtuse( as it's one angle is greater than 90°) as well as isosceles (as it's two sides are equal).
When leading coefficient is 1 , the root will be an integer for g(x) = 0
Option 4 is the right answer.
<h3>What is a Polynomial Function ?</h3>
Functions of independent variable in which the variable can appear more than once with different powers.

Let this represents the polynomial function
where 
Then the according to rational root theorem ,
The root of the function is given by

So when leading coefficient is 1 , the root will be an integer for g(x) = 0
Option 4 is the right answer.
