which relation describes a function?
a) {(0, 0), (0, 2), (2, 0), (2, 2)}
b) {(−2, −3), (−3, −2), (2, 3), (3, 2)}
c) {(2, −1), (2, 1), (3, −1), (3, 1)}
d) {(2, 2), (2, 3), (3, 2), (3, 3)}

B){}

Step-by-step explanation:

A function cannot have replicated x-coordinates. All the other answer choices do, so you would pick this one.

I am joyous to assist you anytime.

(d)

step-by-step explanation:

given: the line in the graph passes through points (5,30) and (6,26).

then, the equation of line is:

now, put y=a(n) and x=n,

hence, option d is correct.
