The book's Try It right after this example: same idea, new numbers. Only the answer is given.

Find the degree of the following polynomials:

How did it go?

ⓐ	$4 x$
The exponent of $x$ is one. $x = x^{1}$	The degree is 1.
ⓑ	$3 x^{3} - 5 x + 7$
The highest degree of all the terms is 3.	The degree is 3
ⓒ	$- 11$
The degree of a constant is 0.	The degree is 0.
ⓓ	$−6 x^{2} + 9 x - 3$
The highest degree of all the terms is 2.	The degree is 2.
ⓔ	$8 x + 2$
The highest degree of all the terms is 1.	The degree is 1.
