Graph the Function with a Graphing Utility and Use It $\lim _ { x \rightarrow 8 } \frac { x ^ { 3 } - 4 x ^ { 2 } - 21 x } { x ^ { 2 } - 15 x + 56 }$

Multiple Choice

Graph the function with a graphing utility and use it to predict the limit. Check your work either by using the table feature of the graphing utility or by finding the limit algebraically. $\lim _ { x \rightarrow 8 } \frac { x ^ { 3 } - 4 x ^ { 2 } - 21 x } { x ^ { 2 } - 15 x + 56 }$

A) $\frac { 15 } { 11 }$
B) $88$
C) $\frac { 11 } { 15 }$
D) 0
E) does not exist
