Write the degree of the following polynomial:
$11-2 y^{2}$

(2) The degree of a polynomial is defined as the highest power of the variable present in the expression.
In the given polynomial $11-2 y^{2}$,the variable is $y$.
The term $11$ can be written as $11y^{0}$,and the term $-2y^{2}$ has a power of $2$.
Comparing the powers $0$ and $2$,the highest power is $2$.
Therefore,the degree of the polynomial $11-2 y^{2}$ is $2$.
