RANGE?

• (-∞,∞)

• [0,∞)

• (-∞,0]

• [-∞,∞]

For the function {(0,1), (1,-3), (2,-4), (-4,1)}, write the domain and range. (Not listed from least to greatest)

• D: {1, -3, -4,}

  R: {0, 1, 2, -4}

• D:{0, 1, 2, -4}

  R:{1, -3, -4}

• D:{0, 1, 2, 3, 4}

  R:{1, -3, -4}

Are these the graphs of two inverse functions?

• Yes

• No

• No way to tell

Are the blue and red graphs inverse functions?

• Yes, the functions reflect over y = x

• No, they do not reflect over the x - axis.
