Solution

Finding degree of polynomial:
A polynomial's degree is the highest or the greatest power of a variable in a polynomial equation.
The given polynomial is $x^{3} + 7 x^{2} + 9 x + 13$ .
Here, the powers of $x$ are $1, 2 a n d 3$ out of which $3$ is the highest. So, the degree of polynomial is $3 .$
Hence, the degree of polynomial $x^{3} + 7 x^{2} + 9 x + 13$ is $3 .$
