Which of the relations below is not a function?
Ilia_Sergeevich [38]

Answer:

Relations B and E do not represent the function.

Step-by-step explanation:

We know that a function is a relation where each input or x-value of the X set has a unique y-value or output of the Y set.

In other words, we can not have duplicated inputs as there should be only 1 output for each input.

If we closely observe relation B, and E i.e.

  • B) {(3,4), (4,5), (3,6). (6,7)}
  • E) {(3,4), (4,5), (4,6)}

Relation 'B' IS NOT A FUNCTION

Relation B has duplicated or repeated inputs i.e. x = 3 appears twice times. we can not have duplicated inputs as there should be only 1 output for each input.

Thus, relation B is NOT a function.

Relation 'E' IS NOT A FUNCTION

Relation E has duplicated or repeated inputs i.e. x = 4 appears twice times. we can not have duplicated inputs as there should be only 1 output for each input.

Thus, relation B is NOT a function.

Therefore, relations B and E do not represent the function.

-6(w - 4) + 8W=6(w + 2)​
Nesterboy [21]

Answer:

w = 3

Step-by-step explanation:

-6(w - 4) + 8W=6(w + 2)​

-6w + 24 + 8w = 6w + 12

2w + 24 = 6w + 12

12 = 4w

3 = w

Which function corresponds to the table of inputs and outputs?
Anarel [89]

Answer:

f(x) = 3x + 2

Step-by-step explanation:

That's easy to find out.  You have your input number, which is your x value, and you have your output number which is your y value (or f(x)).

All you have to do is see if each of the proposed answer works for ALL entries in the data set.

f(x) = 3x + 2  

for x = 3 ===>  11 = 3 (3) + 2 = 11 YES

for x = 5 ===>  17 = 3 (5) + 2 = 17 YES

for x = 7 ===>  23 = 3 (7) + 2 = 23 YES

for x = 9 ===>  29 = 3 (9) + 2 = 29 YES

f(x) = 2x + 5  

for x = 3 ===>  11 = 2 (3) + 5 = 11 YES

for x = 5 ===>  17 = 2 (5) + 5 = 15 NO - we stop here for this function

f(x) = x + 7  

 for x = 3 ===>  11 = (3) + 7 = 10 NO - we stop here for this function

f(x) = 3x + 1

 for x = 3 ===>  11 = 3 (3) + 1 = 10 NO - we stop here for this function
