Answer:

No, each ordered pair in this list has the same first element.

Step-by-step explanation:

A function is a relation in which each possible input value leads to exactly one output value.

Given: G = {(1, 1), (1, 2), (1, 3), (1, 4)}

It has same input (x=1) that leads to multiple outputs (y= 1,2,3,4). This relationship is not a function as per definition provided above.

Correct answer choice is:

No, each ordered pair in this list has the same first element.

Answer:

No, each ordered pair in this list has the same first element.

Step-by-step explanation:

An input can only have 1 output, but multiple inputs can have the same output. How you can check this if you have a graph is if you can draw a straight line (top to bottom) anywhere on the graph and it intersects with the line once or not at all.
