Replacing y by x in the first line we'll get x+8x-12=6, so 9x=18, x=2, y=1 being the only solution
1. Domain (6, 3) to (11, 2)
Range (9,0) to (6,3)
Not a function because two inputs cannot share the same output
2. Domain (1, 50) to (5, 200)
Range (1,50) to (5, 200)
Yes it is a function
The polynomial graph crosses the x-axis at two points and touches x-axis at one point. It indicates the graph has four roots:




The last two roots have equal value as the graph touches the x-axis (not crosses it)
The graph has three unique roots
Just finished this for another student.
Length = 9
I think it’s the second one b
I hope this helps :)
