Identify the sequence graphed below and the average rate of change from n = 0 to n = 3.

Question

abdullah1995 · Answer

for the average rate of change, you have to calculate the slope. so it says from n=0 to n=3. see the y part of these x-coordinates and calculate the slope using the formula$$(y2-y1)/(x2-x1)$$

There is no point for x = 0?

abdullah1995 · Answer

ok then you start from n=2 and end at n=3, since at n=0 and 1 there is nothing on the graph

anonymous · Answer

-5

abdullah1995 · Answer

yes

anonymous · Answer

that's not one of the options though

abdullah1995 · Answer

what are the options available ?

abdullah1995 · Answer

oh you posted them ok let me see 1 min

anonymous · Answer

ok  lol

abdullah1995 · Answer

ok so looking at the options, the answer is either going to be part B or part D

abdullah1995 · Answer

i know this because i plugged the x-co-ordinate in the series and then calculated if i get the same y value that is on the graph

anonymous · Answer

shouldnt it be b since it has a negative slope?

abdullah1995 · Answer

yes. that is correct. it is b because it has a negative slope but let's go ahead and solve this properly

abdullah1995 · Answer

the value for n=0 and n=1 is not shown on the graph because it is too big

abdullah1995 · Answer

in the series plug in 0 and 1 and see what you get
