Which graphs represent functions? A. Graph D only
B. Graph A only
C. Graph C and Graph D
D. Graph B and Graph D

D. graph b and d

Step-by-step explanation:

graph a and c are not functions because there are multiple points with the same number for x

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)
