What is the y-intercept of the equation f(x) = x - 3?

• 1

• -3

• 3

• x

Solve the equation for y. 
2x + 3y = 4

• y = (4-2x)/3
• y = (2x-4)/3
• x  = (4-3y)/2
• y = (4-2x)/ -3

|2a - 10| = 6

• a = 8, a = 5
• a = 2
• a = 8
• a = 8, a = 2

|v + 8| − 5 = 2

−6 < 2t − 5 < 3

• −0.5 < t < 1

• 0.5 < t < −1

• −11/2 < t < 2

• 11/2 < t < −2

Solve and graph:

• A
• B
• C
• D

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.

Is this mapping a function or not a function? 

• Function
• Not a Function 

For the function f(x) = -3(x-1) find f(0).

• 0
