Review for Semester Exam

Solve: 2(4x-3) - 8 = 4 + 2x

• x=5/3

• x=3

• x=1

• x=2

Solve: 5x + 15 = 10x - 40

• x = 10

• x = -10

• x = 11

• x = -11

What is the domain of the following graph?

• -3 < y ≤ 2

• -5 ≤ x <2

• -3 ≤ x < 2

• -5 ≤ y < 4

The following graph is a linear function. Which equation is best represented by this graph?

• y = ⅔x + 1

• y = -2x + 1

• y = -⅔x + 1

• y = 2x + 1

What is the slope in y= -3x + 4

• 4

• -3

• 3

• -1/3

Solve the inequality
x - 2 < 5

• x < 3
• x ≥ 7
• x < 7
• x ≤ 7

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.

• Vertical Line Test

• Ordered Pairs

• Mapping Diagram

• Function Notation

6x - 4 ≥ 26

• x ≥ 3.67
• x ≥ 5
• x < 5
• x ≤ 5

Do you flip the sign?
-3x + 2  ≤  22

• YES
• NO
