Question

Can someone please tell me what goes in the y spot

Answer 1

Answer:

Step-by-step explanation:

Given the function

y = —⅔x + 7

The domain of the function is

The input,

x = { -12, -6, 3, 15}

When x = -12 what is y

y = —⅔x + 7

y = — ⅔ × — 12 + 7

Note that, - × - = +

y = 8 + 7

y = 15

Then, when x = -12, y = 15

When x = -6

y = —⅔x + 7

y = — ⅔ × — 6 + 7

Note that, - × - = +

y = 4 + 7

y = 11

Then, when x = -6, y = 11

Also, x = 3

y = —⅔x + 7

y = — ⅔ × 3 + 7

Note that, -×+ = -

y = —2 + 7

y = 5

Then, when x = 3, y = 5

Also, x = 15

y = —⅔x + 7

y = — ⅔ × 15 + 7

Note that, - × + = -

y = — 10 + 7

y = —3

Then, when x = 15 , y = —3

This is one to one mapping

x= -6 y= 11

x= 3 y= 5

x= 15 y= -3

x= -12 y=15

Answer 2

Answer:

x= -6  y= -12

x= 3   y= 5    

x= 15  y= 15

x= -6  y=15
