Please help on this one?

Answer:

B. g(x)

Step-by-step explanation:

g(x) is a function of odd degree, so its minimum value is -∞, which is far less than the minimum value of -2 that f(x) has.

_____

Any even-degree term (with a positive coefficient) will have a minimum value of zero, hence the minimum value of f(x) is the constant added to the 4th degree term.

Simplify: 3a²b + 5ab – 4ab + ab² + 8a²b

Lisa [10]

In order to simplify this expression, we need to add the like terms.

Like terms are terms that have the same variables to the same power.

So we have:

$\begin{gathered} 3a^2b+5ab-4ab+ab^2+8a^2b \\ =(3a^2b+8a^2b)+(5ab-4ab)+ab^2 \\ =11a^2b+ab+ab^2 \end{gathered}$

Therefore the correct option is the fourth one.
