Algebra.Com's Answer #18585 by stanbon(75887)![]() ![]() ![]() You can put this solution on YOUR website! You have to know what the graph of y=logx looks like. \n" ); document.write( "Do you see that it passes through the point (1,0)? \n" ); document.write( "Then, the (x+4) in your equation moves the graph 4 units to \n" ); document.write( "the left, so the graph passes through (-3,0) \n" ); document.write( "then the \"3\" in your equation multiplies the y-values by \"3\". \n" ); document.write( "The 3 has no effect on the point (-3,0) because y=3(0)=0 \n" ); document.write( "but all the other y-values are multiplid by 3. \n" ); document.write( "The vertical asymptote is x=-4 \n" ); document.write( "The y-intercept is gotten by letting x=0 \n" ); document.write( "So the y-intercept is y=log(5)4=0.86... \n" ); document.write( "Hope this helps. \n" ); document.write( "Cheers, \n" ); document.write( "stan H. \n" ); document.write( " |
