Algebra.Com's Answer #340 by khwang(438) ![]() You can put this solution on YOUR website! Since any denominator cannot be 0, \n" ); document.write( " so x-3 cannot be 0 in y=G(x)= 1 + 2/(x-3)^2 and 3 should be \n" ); document.write( " excluded from the domain of G. \n" ); document.write( " Hence,the domain of G = R -{3} = (-oo,3) U(3,+oo) \n" ); document.write( " Next,we see that 2/(x-3)^2 > 0 for all real x, so G(x) > 1+0 = 1. \n" ); document.write( " So, the range of G is (1, +oo) \n" ); document.write( " \n" ); document.write( " When x =0, G(0) = 1 + 2/9 = 11/9 is y-intercept. \n" ); document.write( " Since y=G(x) >0 for all x, there are no x-intercepts of y=G(x). \r \n" ); document.write( "\n" ); document.write( " The denominator in G(x) is x - 3= 0, which is a vertical asymptote \n" ); document.write( " of G. \n" ); document.write( " As x--> +oo, G(x) --> 1.So, a horizontal asymptote is y=1. \n" ); document.write( " \n" ); document.write( " |
