Algebra.Com's Answer #60544 by stanbon(75887) ![]() You can put this solution on YOUR website! let f(x)=5/x^2 and g(x)=6x+1 \n" ); document.write( "now it says to find (f 0 g)(x) and to find the domain of these \n" ); document.write( "-------------- \n" ); document.write( "(fog)(x) means f[g(x)] \r \n" ); document.write( "\n" ); document.write( "= f[6x+1]\r \n" ); document.write( "\n" ); document.write( "= 5/(6x+1)^2\r \n" ); document.write( "\n" ); document.write( "==================== \n" ); document.write( "Domain: \n" ); document.write( "Since 6x+1 is in the denominator and since the denominator \n" ); document.write( "cannot be zero, 6x+1 cannot be 0 \n" ); document.write( "So 6x cannot be -1 \n" ); document.write( "And finally, x cannot be -1/6 \n" ); document.write( "------ \n" ); document.write( "Domain of (fog)(x) is all Real Numbers except x=-1/6 \n" ); document.write( "=============== \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( " \n" ); document.write( " |
