Answer 1

if you have ln(n), what must n be?

Answer 2

base?

Answer 3

what do you mean?

Answer 4

ok so f(x) is ln(x^2 −10x)

and i found f'(x)=2(x-5)/x(x-10)

Answer 5

now the questions asks for domain for f

Answer 6

of*

Answer 7

you don't use derivative to find the domain of f

Answer 8

can you take ln(-4), ln(-3) , ln(-0.2), ...?

Answer 9

that was the first part of question

Answer 10

no

Answer 11

how about ln(0) ?

Answer 12

so have you found the domain of f yet?

Answer 13

yupp i got it

Answer 14

ok

Answer 15

(-\[(-\infty, 0) and (10, \infty)\]

Answer 16
