Algebra C and C Unit 2

What is the Domain?

• -3 ≤ x < 5
• -3 ≤ y < 5
• -8 ≤ x < 5
• -8 ≤ y < 5

Which representation shows y as a function of x?

• A, C, D

• A, B, C

• A, B, C, D

• B, C, D

What is the Range?

• All real numbers
• y ≥ 3
• y > 3
• 3 ≤ y ≤ 8

Is this a Function?

Why or Why Not?

• The graph does represent y as a function of x because the x values do not repeat.

• The graph does NOT represent y as a function of x because the x values repeat.

• The graph does represent y as a function of x because the y values do not repeat.

• The graph does NOT represent y as a function of x because the y values repeat.

What is the ZERO of the function?

• (0, 2)

• (2, 0)

• (1,0)

• (0, 1)

Which graph represents 2x + 3y = 3?

• 
• 
• 
• 

• -2

• 2

A sequence can be generated using f(x) = 3 + f(n-1), where f(1) = 2. What are the first four terms.

• 3, 5. 7, 9

• 2, -1, -4, -7

• 2, 5, 8, 11

• 3, 6, 9, 12

Look at the sequence. Which expression represents the nth term? 25, 21, 17, 13

• f(1) = 25 f(n) = f(n-1) + 4

• f(1) = -4 f(n) = f(n-1) + 25

• f(1) = 25 f(n) = f(n-1) - 4

• f(1) = -4 f(n) = f(n-1) + 25
