Answer:

A - Not Function

B - Function

C - Function

D - Not Function

E - Function

Step-by-step explanation:

For a relation to be a function, each value of input should have exactly one output. Which means that for one value of x, there should only one value of y. If the relation has repetition of x in its ordered pairs, it means that for one value of x, there are two or more values of y, hence the relation is not a function

(Consult the diagram below)

<h3>A - {(6,12),(3,1),(−1,13),(6,4)} </h3>

As x = 6 is being repeat, it means that x=6 has two values of y that are 12 and 4. IT IS NOT A FUNCTION.

<h3>B - {(−1,−2),(−4,−4),(0,−5),(7,−5)} </h3>

No repetition of x, IT IS A FUNCTION.

<h3 /><h3>C - {(−5,1),(4,10),(5,10),(6,7)} </h3>

No repetition of x, IT IS A FUNCTION.

<h3 /><h3>D - {(−1,4),(1,6),(−1,−2),(0,7)} </h3>

As x = -1 is being repeat, it means that x=-1 has two values of y that are 4 and -2. IT IS NOT A FUNCTION.

<h3>E - {(−2,8),(2,1),(−4,8),(7,9)}</h3>

No repetition of x, IT IS A FUNCTION.

          <u>  252  </u>    * 9 x 28 
              238 
           <u>   224 </u>   * 8 x 28
                14

2758 ÷ 28 = 98 14/28  simplified to 98 1/2
