Answer:
Figure J does not show y as a function of x ⇒ D
Explanation:
y is a function of x if and only if every x has only one value of y
Let us check each given figure if it shows a function or not
#Figure F
∵ Every value of x has an arrow is pointed to one value of y
∴ Every x has only one value of y
∴ The figure shows y as a function of x
#Figure G
∵ The ordered pairs have different values of x-coordinates
∴ Every x-coordinate has only one value of y-coordinate
∴ The figure shows y as a function of x
#Figure H
∵ Every x in the table appears once
∴ Every x has only one value of y
∴ The figure shows y as a function of x
#Figure J
∵ The ordered pairs were drawn in the figure are (-3, -2), (-3, -3), (-2, 0),
(-2, -1), (-1, 1), (-1, 2), (0, 3), (0, 4)
∵ x = -3 has two values of y, y = -2 and -3
∵ x = -2 has two values of y, y = 0 and -1
∵ x = -1 has two values of y, y = 1 and 2
∵ x = 0 has two values of y, y = 3 and 4
∴ Every x-coordinate has more than one value of y-coordinate
∴ Figure J does not show y as a function of x
