Find the inverse of f(x) = -4x - 12

• f^-1(x) = 4x - 3
• f^-1(x) = -1/4x - 3
• f^-1(x) = 1/4x + 3
• f^-1(x) = -4x - 3

What is the DOMAIN of this graph?

• x < -3

• x ≤ -3

• x > -3

• x ≥ -3

Is this graph a function or not a function? 

• Function 
• Not a Function 

What is the DOMAIN?

• [0, ∞)
• (-∞, 0)
• All real numbers
• {0, 1, 2, 3, 4,...}

Factor completely:
2x³ + 5x² - 8x - 20

• (x² - 4)(2x + 5)
• (2x - 5)(x² + 4)
• (2x² - 4)(x + 5)
• (x - 2)(x + 2)(2x + 5)

• Yes

• No

• Maybe

• Cannot be determined

Solve for x
l x−6 l + 4= 10

• x = 12 and x = 0
• x = 3 and x = -3
• x = -12 and x = 0
• No Solution

What's a way to define absolute value?

• The value of a number
• The opposite of a number
• The distance of a number from zero
• The multiplicative inverse of a number

3| −8x| + 8 = 80

• {-7/3, 7/3}
• {-3,3}
• {11/3,-11/3}
• No Solution
