Algebra.Com's Answer #107490 by nerdybill(7384)![]() ![]() You can put this solution on YOUR website! 1. If f(x)=4x^2-3x+2, find f(-1) \n" ); document.write( "All you need to do is replace x with -1 and solve: \n" ); document.write( "f(x)=4x^2-3x+2 \n" ); document.write( "f(-1)=4(-1)^2-3(-1)+2 \n" ); document.write( "f(-1)=4+3+2 \n" ); document.write( "f(-1)=9 \n" ); document.write( ". \n" ); document.write( "2. State the domain of f(x)=(x+3)/(x-1) \n" ); document.write( "Domain specifies all values of x for this equation. \n" ); document.write( "The ONLY time this equation will NOT be defined is IF the denominator (x-1) goes to zero. \n" ); document.write( "Therefore, to find where this equation is NOT defined set it to zero and solve: \n" ); document.write( "x-1=0 \n" ); document.write( "x = 1 \n" ); document.write( ". \n" ); document.write( "From the above, \n" ); document.write( "domain of x is \"all real numbers EXCEPT 1\"\r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
