Which table represents a function

Table C.

Step-by-step explanation:

A function always defines the relationship of input and output. For every input value function defines exactly one output value.

It reveals that for same values of input there can not be different values of output.

Table (A) For input value x = 1 there are two values of output f(x) = 9 and 15. So not the function.

Table (B) For input value x = 1 different values of output = 4 and 5. So not the function.

Table (C) In this table for every value of input there are different values of output so defines a function.

Table (D) For input value x = 0 there are two different output value f(x) = 2 and 5. so it is not a function.

yes

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)
