Question

HOW DO YOU FIND THE DOMAIN:
find the domain of f (x) :


f(x)= 4/ x+3

Answer 1

is it (4/x)+3 or 4/(x+3) ?

Answer 2

4 OVER (x+3)

Answer 3

check where the function cannot be define.

in this case,denominator cannot be zero.
therefore x cannot be equal to -3.

hence, the domain is all real number except -3
