Given f(x) = 2x² + 5x - 17, find f(-1).

• f(-1) = -20

• f(-1) = -24

• f(-1) = -14

• f(-1) = -10

For the function {(0,1), (1,-3), (2,-4), (-4,1)}, write the domain and range.

• 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}

Does this mapping represent a function? Why or why not?

• Yes, this is a function because all the x values are different.

• No, this is not a function because not all the x values are different.

• Yes, this is a function because all the y values are different.

• No, this is not a function because not all the y values are different.
