Question 76906: Hi, I have this graph, and it's y-axis goes from -5 to +10. The x-axis goes from +5 to -5. The first section of the graph is a semicircle. It starts a (-3,0) and ends at (3,0). The highest part of the semicircle is at (0,3). Then the second part of the graph is a horizontal line. It starts at (3,0) and ends at (4,4). The slope of that line should be four. Then the third part of the graph should go from (4,4) to (5,0). The slope should be -4. Then the fourth part of the graph should start at (5,0) and end at (6,1). The slope should be 1. The fith part of the graph should be a horizontal line starting at (6,1) and ending at (7,1). Then the final part of the graph starts at (7,1) and ends at (9,0). If you graphed it, it should look like a semicircle, a triangle, and a trapezoid. The x-axis acts as the base in all the shapes. With that graph, I need to find the equation of the line of symmetry for the graph of above each of the following interval if one exists:
[-3,3]________ [3,5]________ [5,9]_________ [-3,9]_________. I have tried to look for the equations, but I have gotten no where. To be honest, I don't even know what the line of symmetry is. Please help me.
Thank You,
