Find the Domain of g(x) = [x^4 -2x^3 + 7] / [3x^2 – 10x – 8]
\n" ); document.write( "Need to find out when the denominator is zero:
\n" ); document.write( "3x^2-10x-8=0
\n" ); document.write( "3x^2-12x+2x-8=0
\n" ); document.write( "3x(x-4)+2(x-4)=0
\n" ); document.write( "(x-4)(3x+2)=0
\n" ); document.write( "x=4 or x=-2/3
\n" ); document.write( "Domain is all real numbers except x=4 and x=-2/3
\n" ); document.write( "======================
\n" ); document.write( "and f(x) = [x+1]^(1/2) / x.
\n" ); document.write( "x in the denominator cannot be zero
\n" ); document.write( "x+1 must be >=0
\n" ); document.write( "x>=-1
\n" ); document.write( "Domain is all Real Numbers greater than or equal to -1 excluding zero.
