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. :(

  • Algebra - ,

    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

  • Algebra - ,

    suck it perros
