Algebra I Keystone

A relation is shown below:
{(2, 140), (5, 350), (14, 960)}
What is the domain of the relation?

• {2, 5, 14}
• {140, 350, 960}
• {all whole numbers from 2 to 14}
• {all whole numbers from 140 to 960}

The greatest common factor (GCF) of 2 monomials is 3x²y.  One of the monomials is 3x⁴y.  Which could be the other monomial?

• 3xy²
• 6x²y³
• 9x⁶y²
• 18x⁶y²

Simplify: 
(3x²+8x-8)-(-x²+6x+4)

• 2x²+8x-4
• 2x²+8x-12
• 4x⁴+8x-4
• 4x²+2x-12
