QUESTION #1

Use the graphs to find the following. (If an answer does not exist, enter DNE.)Thexy-coordinate plane is given. A curve in three parts and a vertical dashed line are graphed.

• The first part of the curve enters the window just above thex-axis,goes up and right becoming less steep, changes direction at the approximate point(2.2, 0.35),goes down and right becoming more steep, and ends at a closed point on the origin.
• The second part of the curve starts at the open point(0, 1.11),goes up and right becoming more steep, exits almost vertically just to the left ofx= 3,reenters almost vertically just to the right ofx= 3,goes down and right becoming less steep, and exits the window almost horizontally above thex-axis.
