Is this relation a function? justify your answer .

Answer/Step-by-step explanation:

No, because two points with same x values have different y values. The x values cannot be the same but have different y values. This similar to putting a red piece of paper in a machine and out come a blue paper airplane instead of the input being a red piece of paper and the output a red paper airplane.

No because 2 points with the same y-value

have different y vaules

Step-by-step explanation:

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)
