Multiplechoice questions may continue on the next column or page find all choices before answering. Remember to bubble in your EID and VERSION NUMBER. Otherwise its very difficult for me or for Quest to as sign a grade. JEG 001 10.0 points Which one of the following conic sections has graph 1 2 3 4 1 2 1 2 1 2 3 4 1. 9 x 2 18 x 4 y 2 8 y = 41 2. 4 x 2 8 x + 9 y 2 + 18 y = 23 correct 3. 4 x 2 8 x + 9 y 2 18 y = 23 4. 9 x 2 + 18 x 4 y 2 8 y = 41 5. 9 x 2 18 x 4 y 2 + 8 y = 41 6. 4 x 2 + 8 x + 9 y 2 + 18 y = 23 Explanation: The graph is a shifted ellipse centered at (1 , 1) whose major axis has length 6 and minor axis has length 4. Thus one equation for this ellipse is ( x 1) 2 9 + ( y + 1) 2 4 = 1 , which after expansion and simplification can be rewritten as 4 x 2 8 x + 9 y 2 + 18 y = 23 ....
