If f (x) = 3x + 5/x, what is f(a+ 2)?

From the inequality given:

Solving:

\frac{-16}{-\frac{1}{2}} p>32" class="latex-formula" id="TexFormula2" src="https://tex.z-dn.net/?f=-%5Cfrac%7B1%7D%7B2%7Dp%20%3C-16%5C%5C%5C%5Cp%3E%5Cfrac%7B-16%7D%7B-%5Cfrac%7B1%7D%7B2%7D%7D%20%5C%5C%5C%5Cp%3E32" title="-\frac{1}{2}p <-16p>\frac{-16}{-\frac{1}{2}} p>32">

Therefore, the answer is the first number line.
