I think its 149/ 490. Not sure, but pretty confident. Hope this helps.
When you look at the table, find the y value that has equivalent values on both sides. For example, the y value for the vertex here is 10. After it, the values are 7,-2, and 17, and above it, the values are 7 and -2. This value should also be either the largest y value or smallest y value (depending on whether the parabola opens up or down).
The coordinates of r is ( 4, -1 )
Hope the answer I gave you helps!!!
