Plz fast do the ordered pairs listed below represent a function ((3,2) , (4,-1), (3,5), (2,6)) yes or no? why?

First, every time when you ask question like this about function you must give elements of the initial set.

Definition of the function is - Every element of the starting set (domain- x)

must be related to only one element of the second set ( codomain-range-y).

In your case you have element (coordinate) x=3 which is in the relation with two elements (coordinates) y=2 and y=5 and that is relation but not function.

Good luck!!!

answer

see attachment

explanation

the given function is

this function has y-intercept at

-4 and a slope of 2.

note that, the graph has a positive slope.

the graph that represents this function is the straight line that moves upward from left to right.

the graph touches the y-axis at -4.

the correct choice is the graph shown in the attachment.

a) 0.25x times 3. (could be wrong on equation.)

b) 2.25 pound of dark chocolate. (can i eat all the chocolate? plz? anyway, again, could be wrong, but i hope im right. all the chocolate together should be 5.25 pounds)

have a good day!
