document.write( "Question 835546: The rational function has a y-intercept of 7. What is the equation for this function. It shows it with a graph. There are two dotted lines. One is vertical the other is horizontal. They meet at point (-2,5) I don't know if that helps ;( I really need help! \n" ); document.write( "

I'm guessing that the vertical asymptote occurs at \"x=-2\" which means the function doesn't exist there so \"x%2B2\" must be in the denominator.
\n" ); document.write( "The horizontal asymptote occurs at \"y=5\".
\n" ); document.write( "SO the function looks something like,
\n" ); document.write( "\"f%28x%29=5%28%28x%2Ba%29%2F%28x%2B2%29%29\"
\n" ); document.write( "when \"x=0\", \"y=7\"
\n" ); document.write( "\"f%28x%29=5%28%280%2Ba%29%2F%280%2B2%29%29=7\"
\n" ); document.write( "\"%285a%29%2F2=7\"
