Answer 8

@phi

Answer 9

did you find the slope between the first and last points ?

Answer 10

@phi no I just got B, but Im not sure if its right

Answer 11

?

Answer 12

i got 37/4

Answer 13

but i don't think thats right

Answer 14

can you just tell me if B is right, because i did all the work and i am just want to make sure

Answer 15

i used the distance formula for the first and last points

Answer 16

I was assuming they wanted the slope between the points on the graph, but they want between n=0 and n=3

so we need to first find those points.

but, we can see the curve is going down as we move to the right. that means the slope is negative.

Answer 17

so it's either choice A or B

to find out,you could test the formulas

Answer 18

I did and I got B, but I still wasn't sure

Answer 19

Yes, B works. We could try to figure out exactly what the slope is... but knowing it's negative is all we really need to pick choice B.
