Use a CAS to Plot the Function near the Point $\lim _ { x \rightarrow a } \frac { g ( x ) } { f ( x ) } = \frac { g ( a ) } { f ( a ) }$

question 24

Multiple Choice

Use a CAS to plot the function near the point x0 being approached. From your plot guess the value of the limit.
-Write the formal notation for the principle "the limit of a quotient is the quotient of the limits" and include a statement of any restrictions on the principle.

• A) \(\lim _ { x \rightarrow a } \frac { g ( x ) } { f ( x ) } = \frac { g ( a ) } { f ( a ) }\).
• B) If \(\lim _ { x \rightarrow a } g ( x ) = M\) and \(\lim _ { x \rightarrow a } f ( x ) = L\), then \(\lim _ { x \rightarrow a } \frac { g ( x ) } { f ( x ) } = \frac { \lim _ { x \rightarrow a } g ( x ) } { \lim _ { x \rightarrow a } f ( x ) } = \frac { M } { L }\), provided that \(L \neq 0\).
• C) If \(\lim _ { x \rightarrow a } g ( x ) = M\) and \(\lim _ { x \rightarrow a } f ( x ) = L\), then \(\lim _ { x \rightarrow a } \frac { g ( x ) } { f ( x ) } = \frac { \lim _ { x \rightarrow a } g ( x ) } { \lim _ { x \rightarrow a } f ( x ) } = \frac { M } { L }\), provided that \(f ( a ) \neq 0\).
• D) \(\lim _ { x \rightarrow a } \frac { g ( x ) } { f ( x ) } = \frac { g ( a ) } { f ( a ) }\), provided that \(f ( a ) \neq 0\).
