Pre-calculus Chapter 1 Review

What are the domain and range of the relation {(-1,-2), (1,-2),(3,1)}? Is the relation a function?

• D={-1,1,3}; R={-2,1}; yes
• D={-2,1}; R={-1,1,3}; no
• D={-1,-2,3}; R={-1,1}; no
• D={-2,1}; R={-2,1}; yes

Given f(x) = x² + 2x, find f(a - 3).

• a² - 4a + 3
• a² + 2a - 15
• a² + 8a + 3
• a² - 4a + 6

If f(x) = x/(x - 3) and g(x) = 2x - 1, find (f - g)(x).

• (-2x² + 8x - 3)/(x - 3),  where x cannot equal 3
• (-2x² + 6x + 1)/(x - 3),  where x cannot equal 3
• (-2x² + 5x - 3)/(x - 3),  where x cannot equal 3
• (2x² + 6x + 3)/(x - 3),  where x cannot equal 3

What type of slope does the line x = -2 have?

• Positive 
• Negative 
• Zero
• Undefined
