" largest value when x = 3"

- misssunshinexxoxo

We need to work out each of these to determine the answer

- SolomonZelman

Plug in x=3 into each function to find the answer

- SolomonZelman

the function that will give you the biggest output after plugging 3 for x, is the answer you want.

D

- triciaal

is this really 2 questions?
the largest value is as described by @SolomonZelman
plug x = 3 then which is greatest

- anonymous

is it c

- SolomonZelman

option C, or c(x), or what?

- anonymous

option c

- anonymous

check again

- anonymous

no im sorry ihad got confused but my option is a

- anonymous

are u sure what is 9 times 3

- anonymous

27

- anonymous

yes what is 12*3

- anonymous

36

- anonymous

does 27=36

- anonymous

yes

- anonymous

no 27 doesnt equal 36

- triciaal

the largest value when x = 3?
All the functions are equal at x = 3.

- anonymous

isaid that

- anonymous

it cant be A. all the functions are equal at x=3 bc 27 doesnt equal 36

- anonymous

is it option d

- SolomonZelman

maybe it is option z, where \(\displaystyle \lim_{z \rightarrow \infty} z\)

- SolomonZelman

there is no option d, here...

- triciaal

oh I got it " All the functions are equal at x = 3." that was one of the options.
the correct answer is c(x)

- SolomonZelman

Oh, tricial, tnx:)

- anonymous

yes

- SolomonZelman

didn't know it was an option. My bad

- anonymous

- anonymous

Don"t forget to medal and fan if you already haven't. Plus mention me for more help @megan1978
