Multiple Choice

Use a graphing utility to graph the function $f ( x ) = \sqrt { x } + \cos \frac { x } { 2 } \text { and locate the }$ absolute extrema of the function on the interval $[ 0,2 \pi ]$

• A) left endpoint: \(( 0,1.000 )\) absolute minimum right endpoint: \(( 2 \pi , 1.507 )\) absolute maximum critical points: none
• B) left endpoint: \(( 0,0.000 )\) absolute minimum right endpoint: \(( 2 \pi , 2.507 )\) absolute maximum critical points: none
• C) left endpoint: \(( 0,1.000 )\) absolute minimum right endpoint: \(( 2 \pi , 1.507 )\)
• critical points: \(( 1.729,1.964 )\) absolute maximum
• D) left endpoint: \(( 0,2.507 )\) absolute maximum right endpoint: \(( 2 \pi , 0.000 )\) absolute minimum critical points: none
