Question

f(x)=x^2-16 g(x)=x+4 what is f/g and the domain?
if im right, x^2-16 = ((x+4)(x-4))/x+4. x+4 cancels out and leaves you with (x-4)

Answer 1

i will give you a medal

Answer 2

you are right

Answer 3

although you still have to specify the "domain"

Answer 4

the chat thing keeps covering the post button how to i make it stop!!!!!

Answer 5

and im not sure a question i had earlier the domain was -infinity to infinity

Answer 6

its not restricted by any value of x

Answer 7

yes it is

Answer 8

you started with \[\frac{x^2-16}{x+4}\]
you cannot divide by 0 so solve \(x+4=0\) for \(x\) and then say "all real number except..."

Answer 9

except what?

Answer 10

-4?

Answer 11

right

Answer 12

thanks
