Unit 1 & 2 Review

What is the Range?

• y ≥ 6
• y ≤ 6
• -10 ≤ y ≤ 6
• -10 ≤ x ≤ 6

What is the Domain?

• All real numbers
• x > 3
• x = 4
• x ≥ 3

What is the range?

• -4 < x ≤ 5

• -4 ≤ x < 5

• -3 < y < 3

• -3 ≤ y ≤ 3

What is the DOMAIN of this graph?

• -7<x<5

• -7≤x<5

• -3<y<1

• -3≤y<1

For the function {(0,1), (1,-3), (2,-4), (-4,1)}, write the domain.
Remember:  Domain is x 
(x,y)

• D: {1, -3, -4,}
  R: {0, 1, 2, -4}
• D:{0, 1, 2, -4}
  R:{1, -3, -4}
• D:{0, 1, 2, 3, 4}
  R:{1, -3, -4}

Does the graph represent a function?
If you have an x value that has 2 "y" values it is NOT a function! 

• Yes, because the vertical line test shows there are no repeating input values
• No, because the vertical line test shows there are repeating input values

Which graph does NOT pass the vertical line test?

• Graph 1
• Graph 2
• Graph 3
• Graph 4
