Answer:

f(-4) = 9

Step-by-step explanation:

To find which expression to use, see which one x = -4 fits in. That is <em>x² - 5</em>, since -4 < 3.

Then, plug in the number: (-4)² - 5

Square: 16 - 5

Subtract: 9

f(-4) = 9

$\bf \cfrac{5}{\frac{1}{6}+\frac{1}{x+1}}\qquad \cfrac{}{\impliedby LCD\textit{ will be 6(x+1)}}\implies \cfrac{5}{\frac{1(x+1)+1(6)}{6(x+1)}}
\\\\\\
\cfrac{5}{\frac{x+1+6}{6(x+1)}}\implies \cfrac{\frac{5}{1}}{\frac{x+7}{6(x+1)}}\implies \cfrac{5}{1}\cdot \cfrac{6(x+1)}{x+7}\implies \cfrac{30(x+1)}{x+7}$

and you can expand the numerator if you wish, it won't be simplified further though.
