anonymous · Answer

that's what it looked like

anonymous · Answer

Is that y = 1/x

anonymous · Answer

its just a standard graph the answers to it are 2 3 5 and 6 the graphs numbered to 11

anonymous · Answer

I utterly have no idea what im doing I just came back to school from injury so im totally lost on the topic

anonymous · Answer

We need to know the y-values at -1 and 1
Average rate of change is basically the slope between the two points that's why we need the y-coordinates

anonymous · Answer

I guess if you can just estimate them from the graph that will give us a close enough answer

anonymous · Answer

i know what slope is i just don't know how to put it in this type of thing what would be your best guess i think its 5

anonymous · Answer

I can't really tell without knowing the coordinates. Like we have (-1, $y_1$) and (1, $y_2$). We need to know $y_1$ and $y_2$ to get slope. 

$$\frac{ f(b)-f(a) }{ b-a }$$ is just another way of writing
$$\frac{ y_2-y_1 }{ x_2-x_1 }$$
It's the same thing, we just need to know the y's to solve.
Can you post a screenshot or photo of the graph?
