A function is a special relationship where each input has a single output.
therefore :
A is not a function; x=0;  ⇒y₁=3; y₂=4
C is not a function; x=2;⇒ y₁=1; y₂=8
D is not a function; x=1;⇒y₁=2, y₂=-3

only B is a function; each input has a single output.

Explain how you can use absolute value to tell whether
kicyunya [14]

Answer:

Let the integers are p and q.

In case both integers are positive or negative, you add the numbers up and apply their sign to the sum.

<u>Examples:</u>

  • 10 + 88 = 98
  • -20 + (-15) = -35

In case one of the integers is negative and one positive.

  • p < 0, q > 0

Use absolute value in this case.

Subtract the numbers and apply the sign of the number with the greater absolute value.

<u>Examples:</u>

  • - 10 + 15 = |15 - 10| = |5| = 5
  • - 15 + 10 = - |15 - 10| = - |5| = -5

State what additional information is required in order to know that the triangles are congruent by SAS
zalisa [80]
<h3>You are correct. The answer is the second choice.</h3>

BC = JC by the single tickmarks shown

CD = CD because of the reflexive property

The angles between these two pairs of sides, that you've marked in the second answer choice, are needed to use SAS (side angle side).

See the diagram below. In the diagram, angle BCD (green) is between segments BC and CD. Also, angle JCD (blue) is between JC and CD.
