Which of these is NOT the same as the others.

• Domain
• X-Value
• Dependent Variable
• Input

For the function f(x)=-2x+13, f(-4)

• 21
• 5
• -8
• 7

For the function f(x)=3(x+1), f(5)

• 16
• 15
• 18
• 9

f(x)=x²-2x+1
Evaluate the function for f(-1).

• f(-1)=4
• f(-1)=0
• f(-1)=2
• f(-1)=-1

Is this a function?

• Yes
• No

Is this a function?

• Yes
• No

Give the domain and range of the relation.
{(-2,-1), (-1,0), (0,-1), (1,0), (2,-1)}

• D: {-2, -1, 0, 1, 2}
  R: {-1, 0}
• D: {-1, 0}
  R: {-2, -1, 0, 1, 2}
• D: {-2, -1, 0, 1, 2}
  R: {-1, -1, -1, 0, 0}
• D: {-2 < x < 2}
  R: {-1 < y < 0}

Solve the literal equation for the given variable. 

• 2A/h
• 2/(h)
• 2Ah
• Ah/2

Solve for a.

• a = pw
• a = p/w
• a = w/p
• a = w + p

Solve for y: 
8x + 4y= 16

• y = -8x + 16
• y = 2x -4
• y = -2x + 4
• y = -8x + 12
