What is the domain of the function (in interval notation): f(x)=(2x^3-5)/(x^2+2x-15)?
\n" ); document.write( "***
\n" ); document.write( "The only restriction here is that the denominator≠0
\n" ); document.write( "set denominator=0, then solve for x
\n" ); document.write( "x^2+2x-15=0
\n" ); document.write( "(x+5)(x-3)=0
\n" ); document.write( "x≠-5
\n" ); document.write( "x≠3
\n" ); document.write( "Domain: (-∞,-5) U (-5,3) U (3,∞) \n" ); document.write( "

\n" );
