question 174

Multiple Choice

Solve the problem.
-Find an equation for the level surface of the function $f ( x , y , z ) = \int _ { z } ^ { y } e ^ { \theta } d \theta - \int _ { x } ^ { \sqrt { 2 } } t d t$ that passes through the point $( 0 , \ln 2 , \ln 4 )$ .

• A) \(e ^ { y } + e ^ { z } - \frac { x ^ { 2 } } { 2 } = - 2\)
• B) \(e ^ { y } - e ^ { z } + \frac { x ^ { 2 } } { 2 } = 2\)
• C) \(e ^ { y } - e ^ { z } + \frac { x ^ { 2 } } { 2 } = - 2\)
• D) \(e ^ { y } + e ^ { z } - \frac { x ^ { 2 } } { 2 } = 2\)
