Question

What is the exponential function modeled by the following table?
a
f(x) = 2x

b
f(x) = x2

c
f(x) = x3

d
f(x) = 3x

Answer 1

is b x^2 and c x^3?? I am confused on how you wrote it

Answer 2

I will just assume unless you tell me otherwise

Answer 3

Yes,it is;sorry about that.@macho14

Answer 4

oh ok thx I figured

Answer 5

how'd your last question go? did you get it right?

Answer 6

Not quite sure yet but I think it is correct.How I don't know yet is due to waiting to get all my questions I have clarified ,
before submitting the assignment, you know...

Answer 7

yeah, this ones confusing, are you sure this is all the information, something seems off

Answer 8

Did you see the screenshot provided ,yet.?

Answer 9

yeah, what do you think the answer is, wait, I see what I did wrong

Answer 10

So, first of all, we know the function f(x) is representative of y values

Answer 11

Well,I think the answer is either between letter choice a or c?

Answer 12

hmm, none of these functions match any of the given points on the table

Answer 13

can you screenshot the whole question?

Answer 14

OOOOOOOH, thats the issue, it's 3^x, not 3x

Answer 15

duh, I should've known, since this is an exponential function

Answer 16

I just ruled out the first and last

Answer 17

thinking that they were wrong

Answer 18

b and c, are not the answer, so that leaves a and c

Answer 19

Sorry about any confusions,@macho14 ,from now on I will try to add more clarity to the posts'.

Answer 20

yeah, it's no problem, I was just confused on how I turned stupid all of the sudden XD

Answer 21

I can totally relate especially in Mathematics,it is one of the worst feelings,at least involving academics you know...Aside from that,did you break it down to the what the value would be as I as well agree that either a or c will be the value,etc.

Answer 22

I have the answer: the right answer is either a or c, plug in the x values on the table for answer a. \[2^x\] plug in first x value. \[2^3\]

Answer 23

it corresponds to the correct f(x) value

Answer 24

\[2^3=8\]\[2^4=16\]\[2^5=32\]

Answer 25

howeverAanswer a looks to be correct, but just to check, let's look at answer d: \[3^3\neq8\]

Answer 26

so \[f(x)=2^x\] must be correct

Answer 27

any questions, you can ask me, gl
