Which of the following graphs of exponential functions corresponds to a geometric sequence with a 1st term of 6 and a ratio of 1/2?
I'm honestly so confused on this. :(
the terms of the sequence are
6 3 1.5 .75 ,...
So, the graph comes down from the upper left, passes through (0,6) and tails off to the right with horizontal asymptote y = 12
I assume one of the displayed graphs looks like that.
If it's not clear how I came up with those numbers, spend a little time reviewing geometric series.
sorry. the asymptote is y=0
suck it perros
