Need this asap i need to find out which is a function but i get really confused on these things

Step-by-step explanation:

Use the "vertical line test."  Draw a vertical line through each graph.  If the line intersects the graph in more than one place, the graph does NOT represent a function.  Only the graph in the upper, right-hand corner represents a function, as a vertical line intersects this graph in only one place.

sorry can't

step-by-step explanation:

i googled though and something came up but it was in science langueage not common english sooo

y > 1/3x

y < = -x + 4

hope this : )
