Does this graph represent a function?

yes (B)

Step-by-step explanation:

use the line method (run a line through the graph if the line meets two points at the same time it is not a function.)

Hope this helps

Yes it does. In fact, it represents a quadratic function ( if right side up next time put it right side up)

Step-by-step explanation:

-8/2y-8=5/y+4-7y+8/y^2-16

we move all terms to the left:

-8/2y-8-(5/y+4-7y+8/y^2-16)=0

we can not solve this equation

f(x)=4
