You can put this solution on YOUR website!
the domain is all real values of x that lead to a real value of f(x).
\n" ); document.write( "you have f(x) = 3/(x+9)
\n" ); document.write( "since (x+9) is in the denominator, then the denominator will be equal to 0 when x = -9.
\n" ); document.write( "the value of f(x) = 3/(x+9) is not defined when the denominator is equal to 0.
\n" ); document.write( "the domain of the function is therefore all values of x except at x = -9.
\n" ); document.write( "
\n" ); document.write( "
