5not a function 6 7 8 function 9 10 i sadly don't know any of the others. hopefully one of you can me. : )

6) Function

7) Not a Function

9) Not a Function

10) Function

Step-by-step explanation:

If one input has 2 different outputs, then it isn't 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)

answer: finding the extract measurements and knowing the points
