Is this table a function??

No

Explanation: In order for a table to represent a function,

each x term must correspond to exactly one y term.

In this case, we have a 49 paired to -7 and a +7.

Since the 49 doesn't correspond to one y term,

this table cannot represent a function.

g = (2, 2)

step-by-step explanation:

given the ratio is 1 : 1 then f is the midpoint of eg

let the coordinates of g = (x, y)

using the midpoint formula

(0 + x) = 1 ( multiply both sides by 2 )

0 + x = 2 ⇒ x = 2

similarly

(4 + y) = 3 ( multiply both sides by 2 )

4 + y = 6 ( subtract 4 from both sides )

y = 2

coordinates of g = (2, 2)
