Question

Log (x^2-7x+12): Find the domain?

Answer 1

I know you gotta set it to 0 :(

Answer 2

I can give you an example. But not the answer. That would be cheating.

Answer 3

Lol, the thing is, I already have the answer I'm just not sure how :(

Answer 4

I got up to (x-3)(x-4) but that's it.

Answer 5

See if this helps you!

Given the rational function: f(x)=7x / x^2-16
a. The domain
When checking domain look for terms with sqrt and zeros in the denominator which would make function undefined. Since there are no sqrts in given equation, check for zeros in the denominator.
x^2-16=0
(x+4)(x-4)=0
x=-4 and x=4
domain:{x|x≠-4, x≠4}, or (-∞,-4) U (-4, 4) U (4, ∞)

Answer 6

Does it help you?

Answer 7

I'm looking at it but you gotta set it to >0 in my example. It's the same format but I dont even know how to set it in interval form

Answer 9

wwhy?

Answer 10

Could you help with this?

Answer 11

i could try but why you pick me...just random ?

Answer 12

Yeah

Answer 13

Answer 14

how odd. the log doesnt matter btw

Answer 15

OH OKAY I REMEMBER WHAT TO DO?

f(x)= log(x^2-7x+6)
x^2-7x<=6 This is not allowed.
x^2-7x-6<=0

Does this help?

Answer 16

So.....
f(x)= log(x^2-7x+12)
x^2-7x<=12 This is not allowed.
x^2-7x-12<=0

Answer 17

In your case^
