Question

find the domain of the function

f(X) = ln(2-x)

Answer 1

domain of this function would be x<=2 since log is not defined for negative values

Answer 2

so it is (- infinity, 2]

Answer 3

got it jsy? or u need more clarification? :):)

Answer 4

sry *jay

Answer 5

Are you there???? @jay

Answer 6

ln is not define for zero either....when does ln(x) = 0?

Answer 7

log 0 = 1 am i right?

Answer 8

if its so, then the answer is (-infinity, 2)

Answer 9

no...sorry :) thats better..

think of it this way. the log points to an exponent:

log2(8) = 3

the exponent is "3" the base is to "2"

2^3 = 8

now tell me....

2^? = 0 ??

Answer 10

log2(0) = ?

Answer 11

then my second option is correct? isn't it? and not the first one...

Answer 12

(-inf,2) is correct :)

Answer 13

hmm.... yay amistre:)

Answer 14

i think jay is not here

Answer 15

jay was just the catalyst.... math goes on without him lol

Answer 16

:)but i think this shud help him

Answer 17

i definitely see that as an option thank u so much

Answer 18

you 're welcome:) any more questions??

Answer 19

\[2-x \ge0\]\[x \le 2\]
hence the domain is \[[-\infty, 2)\]
