Find the limit.
-Let $\lim _ { x \rightarrow 8 } f ( x ) = 1$ and $\lim _ { x \rightarrow 8 } g ( x ) = - 9$. Find $\lim _ { x \rightarrow 8 } [ f ( x ) + g ( x ) ] ^ { 2 }$.
A) $- 8$
B) 82
C) 10
D) 64

The limit of the sum is $\lim _ { x \rightarrow 8 } [ f ( x ) + g ( x ) ] = \lim _ { x \rightarrow 8 } f ( x ) + \lim _ { x \rightarrow 8 } g ( x ) = 1 - 9 = -8$. Squaring this gives $(-8)^2 = 64$.
