For the function (0,1), (1,-3), (2,-4), & (-4,1), which choice gives the correct domain & range?

• D: {0, 1, 2, -4}
  R: {1, -3, -4, 1}
• D: {-4, 0, 1, 2}
  R: {-4, -3, 1}
• D: {0, 1, 2, 3, 4}
  R: {1, -3, -4}
• D:  {-4, -3, 1}
  R: {-4, 0, 1, 2}

Is this a function?  Why or why not?

• No, the domain numbers are repeated.
• No, it passes the Vertical Line Test.
• Yes, it passes the Vertical Line Test.
• Yes, the range numbers are not repeated.

Is this graph a function or not a function? 

• Function 
• Not a Function

Write the equation in point-slope form

for the line that contains the points

(3, -5) and (5, - 1)

• y - 5 = 2(x + 3)

• y + 5 = 2(x - 3)

• y - 3 = 2(x + 5)

• y + 3 = 2(x - 5)

Determine the equation of a line perpendicular to y=-3x-2 and going through the point (9, 2), in slope-intercept form.
