Question

What is the logarithmic function modeled by the following table?

Answer 1

what grade are you in?

Answer 2

I have only learned a little bit of this, that's why I wondered if you were in a higher grade

Answer 3

I tried graphong the given functions, but none of them correspond to any of the points

Answer 4

@hero

Answer 5

So,you are unable to then assist with this question thus far?@macho14

Answer 6

yeah, I will try to do some research and see if I can figure this out, be back later

Answer 7

Oh okay,then.Thank you for helping either way @macho14 .

Answer 8

plug and chug

first take the first coordinate (5,1)

plug it as x and y into each of the four function equations
the ones that do not make each side equal can be eliminated

Answer 9

tell me what you get

Answer 10

Wait to clarify,do you mean the letter choices or of the choices in the table provided,I am quite confused on how you worded it a little...?@snowflake0531

Answer 11

either is okay, it's just so I can check that you did it correctly

P.S. I get a notification when you reply on a post, you do not need to @

Answer 12

Oh I didn't know that,thank you for clarifying on that though.

Answer 13

Plug and chug is not the fastest actually because you have to plug three values into each option. Graphing is faster.

Answer 14

graphing is usually not an option during a test, it's good to know how to do it by hand

Answer 15

Not necessarily true that graphing isn't an option on tests. Yes good to learn to do it by hand if graphing is somehow not an option.

Answer 16

Plug and chug is more of a last resort in this case. As in, you have no other options so you have no choice but to plug and chug.

Answer 17

I figured it out

Answer 18

I know the answer now

Answer 19

just studied up on some stuff

Answer 20

tell me what you think it is @goldwing

Answer 21

also I agree with hero, the plug and chug method is very long

Answer 22

graphing is much quicker for logarithmic functions

Answer 23

the plug and chug method took me approximately five seconds, and it would probably take me two minutes to graph but 👌

feel free to choose your route, I'm out ✌️

Answer 24

ah, I guess I just work quicker on a graph, that's cool tho

Answer 25

Well Snow everyone has there own method of solving things. You think that method is good and hero things the opposite. There both methods that will get you to your answer no matter what.

Answer 26

How about Hero you can show the user your way and snow show the user your way so then the user could solve either way.

Answer 27

can you literally stop

Answer 28

lol, this dude just wants help, let's quit debating

Answer 29

\[f(x)=\log_{5} x=\frac{ \log ~x }{ \log 5}\]
if x=5,f(x)=?
if x=25,log 25=log5^2=2 log5
f(x)=?
