Differentiating a logarithmic function in exercise, find the derivative of the function. see examples 1, 2, 3, and 4.
f(x) = ln {1 + e^x/ 1 - e^x}

The derivative of the function :

Step-by-step explanation:

Identity =

Quotient rule =

Identity =

b. 6

step-by-step explanation:

we are given the table representing an exponential function.

we can see from the table that, as x is increasing, the value of y is increasing in the power of 6.

i.e. the following relation is obtained,

x = 1, y = 6

x = 2, y = 36 =

x = 3, y = 216 =

x = 4, y = 1296 =

x = 5, y = 7776 =

so, the geometric series obtained is .

thus, the common ratio is given by = = 6.

hence, the common ratio is 6.

a is the right answer
