Answer 1

Answer:

B) (x, y) = (-2, 8), (0, 4), (2, 8)

Explanation:

Try the x-values and see what you get.

For x = -2

... x² +4 = (-2)² +4 = 4 + 4 = 8 . . . . . does not match selections A or C

For x = 0

All the choices are in agreement

For x = 2

... x² +4 = 2² +4 = 4 + 4 = 8 . . . . . matches selection B

Thus the only choice listing function values that match the function is ...

... B) x y = -2 8, 0 4, 2 8.
