21x + 28 = 156 - 2
21x = 154 - 28
21x/21 = 126/21
X = 6

What is the asymptote for the graph of this logarithmic function?<br><br> f(x) = log3(x – 1)

Pepsi [2]

Answer:

Vertical Asymptote:

$x=1$

Horizontal asymptote:

it does not exist

Step-by-step explanation:

we are given

$f(x)=log_3(x-1)$

Vertical asymptote:

we know that vertical asymptotes are values of x where f(x) becomes +inf or -inf

we know that any log becomes -inf when value inside log is zero

so, we can set value inside log to zero

and then we can solve for x

$x-1=0$

we get

$x=1$

Horizontal asymptote:

we know that

horizontal asymptote is a value of y when x is +inf or -inf

For finding horizontal asymptote , we find lim x-->inf or -inf

$\lim_{x \to \infty} f(x)= \lim_{x \to \infty}log_3(x-1)$

$\lim_{x \to \infty} f(x)=log_3(\infty-1)$

$\lim_{x \to \infty} f(x)=undefined$

so, it does not exist

Let X1, · · · , Xn be independent identically distributed random variables with probability density function f(x) = 1 2σ exp − |

Answer:

σˆ =

sPn

i=1 X2

Step-by-step explanation:

To obtain, the maximum likelihood ratio, we use the following method.

l(σ) = Xn

i=1 "

− log 2 − log σ −

|Xi

Let the derivative with respect to θ be zero:

(σ) = Xn

i=1 "

−

|Xi

= −

i=1 |Xi

= 0

and this gives us the MLE for σ as

σˆ =

i=1 |Xi

Again this is different from the method of moment estimation which is

σˆ =

sPn

i=1 X2
