Does this graph represent a function? Why or why not?

No, because it fails the vertical line test.

Step-by-step explanation:

If you were to draw a vertical line through the graph at any x-coordinate, it would fail the vertical line test.

For a graph to be a function, it must have only one x value for every y value that was input.

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl
