Question

What function is graphed below?


f(x) = log (x – 3)

f(x) = log (x + 3)

f(x) = log x + 3

f(x) = log x – 3

Answer 1

hint : log(x) cuts x axis at 1

Answer 2

the given graph is cutting x axis at 4

Answer 3

go to this website and type in each equation then click graph and it will graph it for you http://www.meta-calculator.com/online/

Answer 4

so it has slided 3 units to right !

Answer 5

this we simply replace x with (x-3)

log(x) ---- > log(x-3)

Answer 6

log(x) becomes log(x-3) when it slides right by 3 units.

Answer 7

does that make some sense

Answer 8

yes it does . its simpler than i thought ! (:

Answer 9

sounds good :)

Answer 10

Which of the following is equivalent to log 2x 3y

Answer 11

2x is lower by the way . i think its called the subscript.

Answer 12

\(\large \log_{2x} 3y\)

Answer 13

like this ?

Answer 14

yess (: . shhould i type the answer choices to show you??

Answer 15

it wud be a pain to type all.. il show u how it simplifies, see if its there in ur choices ok

Answer 16

thats even better ! (:

Answer 17

use this :-

\(\large \log_b a = \frac{\log a }{\log b }\)

Answer 18

\(\large \log_{2x} 3y = \frac{\log 3y}{\log 2x}\)

Answer 19

do u have it in ur options ha

Answer 20

is it supposed to have parenthesis or no ?

Answer 21

you can have parenthesis like this :-

\(\large \log_{2x} 3y = \frac{\log (3y)}{\log (2x)}\)

Answer 22

yess ! you are reallyyy Smart !!!!!!!!!!!!!!!!!!!!!!!!!! (::

Answer 23

you're smart, not me lol :)

Answer 24

How long it will take for $300 to double when invested at 6% annual interest compounded twice a year?
i got 11.7 . am i right ?

Answer 25

\(300 (1 +\frac{.06}{2})^{2*t} = 600\)

Answer 26

t = 11.7249

Answer 27

you're right ! gw !!

Answer 28

it takes 11.7 years to double the money

Answer 29

Yaaaayy (:. okk im going to open a new thread .

Answer 30

we can continue here if u want... new thread is also fine lol

Answer 31

nooopee. here is fine i have like 3 more on this assigmentt.

Answer 32

Which of the following statements is true?

An exponential function is never the inverse of a logarithmic function.

The base of the logarithmic function f(x) = log5x is unknown.

The range of the logarithmic function f(x) = log5x is all real numbers.

The domain of the logarithmic function f(x) = log5x is all real numbers.

Answer 33

i think c or d im just not sure.

Answer 34

hint : log function cannot take negative values as input

Answer 35

so the domain of log is always positive real numbers oly.
