The parent function f(x)=log10x is vertically stretched by a factor
\n" ); document.write( "of 3, reflected in the y-axis, horizontally transformed 4 units to the left
\n" ); document.write( "and vertically transformed 2.5 units up. What is the equation of the
\n" ); document.write( "vertical asymptote of the transformed function?\r
\n" ); document.write( "\n" ); document.write( "The parent function: \r
\n" ); document.write( "\n" ); document.write( "\"f%28x%29=log%2810%2C%28x%29%29\"\r
\n" ); document.write( "\n" ); document.write( " \r
\n" ); document.write( "\n" ); document.write( "
The vertical asymptote is the y-axis, whose equation is x = 0.

\n" ); document.write( "is vertically stretched by a factor of 3,
\r\n" );
document.write( "\r\n" );
document.write( "So we multiply the entire right side by 3, and call it g(x)\r\n" );
document.write( "\r\n" );
document.write( "\"g%28x%29=3log%2810%2C%28x%29%29\" \r\n" );
document.write( "\r\n" );
document.write( " \r\n" );
document.write( "\r\n" );
document.write( "The vertical asymptote is still the y-axis, whose equation is x = 0.

\n" ); document.write( "reflected in the y-axis,
 \r\n" );
document.write( "We replace x by -x, and label it h(x)\r\n" );
document.write( "\r\n" );
document.write( "\"h%28x%29=3log%2810%2C%28-x%29%29\" \r\n" );
document.write( "\r\n" );
document.write( " \r\n" );
document.write( "\r\n" );
document.write( "The vertical asymptote is still the y-axis, whose equation is x = 0.

\n" ); document.write( "horizontally transformed 4 units to the left
\r\n" );
document.write( "\r\n" );
document.write( "We replace x by (x+4) and label the new function k(x)\r\n" );
document.write( "\r\n" );
document.write( "\"k%28x%29=3log%2810%2C%28-%28x%2B4%29%5E%22%22%29%29\"\r\n" );
document.write( "\r\n" );
document.write( "and remove the inner parentheses:\r\n" );
document.write( "\r\n" );
document.write( "\"k%28x%29=3log%2810%2C%28-x-4%5E%22%22%29%29\"\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Now the vertical asymptote has moved 4 units left, so its equation \r\n" );
document.write( "is x = -4.

\n" ); document.write( "and vertically transformed 2.5 units up.
 \r\n" );
document.write( "We add 2.5 to the entire right side and label the new function m(x)\r\n" );
document.write( "\r\n" );
document.write( "\"m%28x%29=3log%2810%2C%28-x-4%5E%22%22%29%29%2B2.5\"\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "The vertical asymptote is still x = -4.

\n" ); document.write( "What is the equation of the vertical asymptote of the transformed function?
\r\n" );
document.write( "\r\n" );
document.write( "Answer:  x = -4\r\n" );
