Question 878004
Domain is the set of x values where the function is defined.
Square root is undefined when the argument is less than zero.
{{{x^2+7x+12<0}}}
{{{(x+4)(x+3)<0}}}
.
.
.
{{{graph(300,300,-6,2,-4,4,x^2+7x+12)}}}
.
.
.
The function is negative in the range {{{-4<x<-3}}}.
.
.
.
This set of {{{x}}} values is excluded from the domain.
