9514 1404 393

Answer:

  True

Step-by-step explanation:

Make a list of the first number in each ordered pair:

  {-4, 2, 1, -1}

You may want to put these in order. (Not necessary; can be helpful.)

  {-4, -1, 1, 2}

If any values are repeated, the relation is NOT a function.

Here, all the values are different, so this relation is a function.

musickatia [10]

Answer:

In the first one you are missing (x - 3) so it will be 4(x - 3) and if you factor it out it will be 4x - 12

In the second one you are missing a (x -5)which means 9x(x -5) or when you factor it out it will be 9x^2 - 45x

Step-by-step explanation:

3x^2 -23x + 40 = (3x - 8) (x - 5)

3x^2 -17x + 24 = (3x -8) ( x - 3)
