Question

PLEASE HELP. I AM LOST. I HAVE NEVER BEEN HELPED ON THIS SITE. This is my last try. Using the graph of f(x) = log2x below, approximate the value of y in the equation 22y = 4.

Answer 1

y= 2
y= 1
y= 0.47
y= 4.01

Answer 2

;-;

Answer 3

Please don't just give me the answer. I want to know how to do it.

Answer 4

I like this attitude! @Kainui since math is not my field, can u please please help this person????

Answer 5

I feel helpless. It didn't teach us this in the lesson, and I have no idea how to do it. I can't find help anywhere and I won't be able to talk to my teacher until tomorrow. I hate being stuck.

Answer 6

same here ;_;

Answer 7

i know dat feel

Answer 8

@Luigi0210 please? T_T

Answer 9

To get the value of y, you have to get y by itself, so: \(\ y=\frac{4}{22} \) which is \( y=\frac{2}{11} \). Make sense so far?

Answer 10

Yes I understand that part.

Answer 11

Good, so now you have to approximate what 2/11.. do you know what the closet decimal to it is?

Answer 12

I know that 2/11 is like.18181818

Answer 13

0.18181818

Answer 14

But that is no where near any of my answers. I'm confused as to what approximate means in this question.

Answer 15

Is that \(\Large y=log_{2} x\) or \(\Large y=log 2x \) ?

Answer 16

The question shows it as log2x, but the graph shows that the base is actually the 2. So it is log_2 x. Even though the question shows it differently smh.

Answer 17

Did you give up on me?

Answer 18

I'm at a loss, sorry :/

@perl any ideas?

Answer 19

im reading :)
you want to solve 22y = 4 , using the log graph?

Answer 20

It's okay. I'm in the same boat lol. My lesson didn't teach me this, and there are like 4 of these on the practice test I'm taking.

Answer 21

I don't know what the question is asking to be honest. I gave all the options for answers above, I have no idea what to do. I wasn't taught this at all in my lessons.

Answer 22

none of your answers match the question though
can you upload the actual question itself?

Answer 23

Yes. I will screenshot it for you.

Answer 24

ok :)

Answer 25

ok i see it

Answer 26

do you see that none of the answers match the question
22(2) = 44, not 4, and the rest don't match

Answer 27

I guess they made a mistake. I have another if you would like to see it. It is a similar question that I don't know how to do.

Answer 28

i know whats going on, that 2 is raised to the power of y

Answer 29

the equation should be
2^y = 4
