• y= 8x - 1

• y = 3x + 14

Which is the graph of y= -x + 2? 

• A

• B

• C

• D

Factor:
2x² + 11x + 14

• (x + 7)(2x + 2)

• (x + 2)(2x + 7)

• (x + 14)(2x + 1)

• (x + 1)(2x + 14)

What is the domain of the graph?

• -3 ≤ x ≤ 3

• 3 ≤ x ≤ -3

• -2 ≤ x ≤ 10

• -3 ≤ x ≤ 10

Is the relation a function? Why.

• Yes, because the x-value 11 has two y-values pair with it.

• Yes, because each x-value has only one y-value paired with it.

• No, because the x-value 11 has two y-values pair with it.

• No, because each x-value has only one y-value paired with it.

What are the x- intercepts?

• x= 0 and x= -4

• x= 0 and x= 4
