Find the sum of the geometric series.

a
b
c
d

B.

Step-by-step explanation:

We have,

The first term of the series, .

The common difference is given by, i.e. .

Since, the given series is an infinite series, then,

Sum of an infinite series =

i.e. Sum the series =

i.e. Sum the series =

i.e. Sum the series =

i.e. Sum the series =

i.e. Sum the series =

Thus, the sum of the series is .

the slope of the first function is -3. (3/1)

the slope of the second function is 1. (13-10/6-3).

since |-3| is greater than |1|, the function with the steepest slope is the first.
