@carcar3 did you write (on paper) what f / g is?

mathteacher1729 · Answer

In other words @tcarroll010 is saying "The domain is all real numbers EXCEPT the values of x make the denominator = 0." :)

soo out of the four choices what would be the answer

mathteacher1729 · Answer

@carcar3 did you write the fraction f / g ? (with f replaced with x^2-16 and g replaced by x + 4 ?)

anonymous · Answer

yea

mathteacher1729 · Answer

The denominator = the bottom (g, in other words) 

What value of x makes the denominator = 0 ?
