Question

Let = x2 – 16 and g(x) = x + 4. Find and its domain.

Answer 1

Your suppose to do fx/gx

Answer 2

if f(x)=x^2 -16 ???

Answer 3

yeah

Answer 4

f(x)/g(x)=[(x+4)(x-4)/(x+4)]
=x-4

so the domain is \[(-\infty,\infty)\]

Answer 5

thanks

Answer 6

so is the domain all real numbers except \[x\neq4\] or \[x \neq-4\]

Answer 7

which one would be correct?

Answer 8

You there?

Answer 9

when you ploting the graph y=x-4 so both of your graph is approach to infinity so.
it can,t be \[x \neq 4\]
so the value of domain is \[(-\infty,\infty)\]
