Question

Which relation is represented by the arrow diagram?
(Points : 1)
{(4, –3), (5, –1), (7, 0), (2, 2), (7, 5)}
{(4, –3), (5, –1), (0, 7), (2, 2), (5, 7)}
{(–3, 4), (–1, 5), (0, 7), (2, 2), (5, 7)}
{(–3, 2), (–1, 4), (0, 4), (2, 5), (5, 7)}

Answer 1

Does each x value have a different y value attached?

Answer 2

And does each y value go into a seperate x coordinate?

Answer 3

idk

Answer 4

Look at (0,7) and (5,7)

they have different x value but the same y coordinates.

What kind of function does that make it?

a function, non function, onto function?

Answer 5

wats a onto function

Answer 6

Scratch that, a onto function is a function that PASSES both the vertical and horizontal line test

Answer 7

To be a onto function, every x and y coordinate must be different.

Answer 8

Here you have two 7's as a y coordinate, so it's not onto.

Answer 9

So is it a function or not?
