Answer:
{(2,5), (3,7), (2, 9) } is not a function
Step-by-step explanation:
It's because the domain, which is the x value, has the same number twice, which is 2.
Root: (0, 0)
Domain: x=R
Y= (0, 0)
8x-2+9-6x=0
2x+7=0
2x=-7
x=-3.5
The answer is 36. Hope I could help you out. If you need an explanation just let me know an I would be happy to help. : )
