Question

HELP FAST PLEASE!

I do not understand please help and explain which ordered pair of 4 options represents a function.

Answer 1

third option represents a function.

Explanation:

for the ordered pairs to represent a function.

each value of x must only map to one unique value of y

in the first option

(- 2, 0 ) and (- 2, 2 )

the same x- coordinate maps to 2 different values of y

thus not a function.

in the second option

every value of x = - 5 maps to 5 different values of y

thus not a function.

in the third option

each value of x maps to a unique value of y.

thus a function.

in the fourth option

(- 6, - 3 ) and (- 6, - 2 )

the same x value maps to 2 different values of y

thus not a function.
