Which of the graphs are not functions? HEPP ME PLSSS!!

Option II: I and III are not functions

Step-by-step explanation:

A function is a relation in which no two ordered pairs have the same input (or x-values) and different outputs (y-values). In other words, a function can only take on one output for each input.

The Vertical Line Test (VLT)allows us to know whether or not a graph is actually a function.  If a vertical line intersects the graph in all places at exactly one point, then the relation is a function.

To use the VLT, imagine dragging a ruler held vertically across the  graph from left to right. If the graph is that of a function, the edge of the ruler would hit the graph only once for every x -value. If you do this for the given graphs, every vertical line intersects the graph in at most one point represents a function. It only takes one input value to associate with more than one output value to be invalid as a function.

As you can see in the edited screenshot, the vertical lines drawn on graph 1 crosses the graph more than once, that is why it is not a function. The 2nd graph is a function, because each vertical line crosses the graph only once.

The 3rd graph is definitely not a function because the vertical line crosses the graph more than once.

Therefore, the correct answer is option II: I and III

"a" determine whether sage found the correct quotient. show your work

step-by-step explanation:

yes

step-by-step explanation:

so of course you want to start by plugging the 5 in which goes to 7(5)+3(5)=50 because 7*5=35 and 3*5=15 and then add them together, then plug in the 5 to the other equation as well 9(5)+5=50 because 9*5= 45 and then add 5 and so yes they are equivalent.
