8-39.

What is the degree of each polynomial function below?

$P(x) = 0.08x^2 + 28x$
Hint (a):
Look for the highest-valued exponent.
Answer (a):
$2$

$y = 8x^2 -\frac{1}{7}x^5 + 9$
Hint (b):
See part (a).

$f(x) = 5(x + 3)(x - 2)(x + 7)$
Hint (c):
If you multiplied the factors to write the function in standard form, what would be the highest power of $x$ ?
Answer (c):
$3$

$y = (x - 3)^2(x + 1)(x^3 + 1)$
Hint (d):
See part (c).
