question 152

Multiple Choice

Algebraically evaluate the limit (if it exists) by the appropriate technique(s) .Round your answer to four decimal places. $\lim _ { x \rightarrow 0 ^ { - } } \frac { \sqrt { x + 2 } - \sqrt { 2 } } { x }$

• A) \(\lim _ { x \rightarrow 0 ^ { - } } \frac { \sqrt { x + 2 } - \sqrt { 2 } } { x } = \frac { \sqrt { 2 } } { 4 } \approx 0.3536\)
• B) \(\lim _ { x \rightarrow 0 ^ { - } } \frac { \sqrt { x + 2 } - \sqrt { 2 } } { x } = \frac { 2 \sqrt { 4 } } { 4 } \approx 1\)
• C) \(\lim _ { x \rightarrow 0 ^ { - } } \frac { \sqrt { x + 2 } - \sqrt { 2 } } { x } = - \frac { 2 } { 4 } \approx - 0.5\)
• D) \(\lim _ { x \rightarrow 0 ^ { - } } \frac { \sqrt { x + 2 } - \sqrt { 2 } } { x } = \frac { 2 } { 4 } \approx 0.5\)
• E) \(\lim _ { x \rightarrow 0 ^ { - } } \frac { \sqrt { x + 2 } - \sqrt { 2 } } { x } = \frac { 4 \sqrt { 2 } } { 2 } \approx 2.8284\)
