Question

what is the domain of f(x)=2 divided by x+3

Answer 1

We cannot divide by zero. So x+3 cannot be zero which means x cannot be ?

Answer 2

replace your equation by x=2

Answer 3

\[f(x)=\frac{ 2 }{ x+3}\]

Answer 4

noe for domain we need that their should not be a value which makes the function infinty
that is here if denominator =0
than 2/0=infinty

Answer 5

and infinity is not defined
so denominator neq 0

Answer 6

\[x+3\neq0\]

Answer 7

\[x \neq -3\]

Answer 8

except this everything is our domain
