PLEASE HELP! does the mapping diagram represent a function? why or why not?

A. No; each output value pairs with two input values.

B. Yes; each input pairs with only one output.

C. No; the input value x= -5 pairs with two output values

D. No; each input pairs with only one output.

fa tha first one you gonna add y to both sides

it look like this

x-y+y=6+y

x=y+6

therefore your answer is

x =y+6

fa tha second one

you gonna flip tha equation

it gonna look like x-4y=y

then add 4 to both sides

it gonna look like tha

x-4 +4 =y +4

so therefore tha answer is x=y+4

step-by-step explanation:

126 maybe. sorry
