You can put this solution on YOUR website!
The domain of the function is the set of all real numbers except x = 7. (Why?) Operating only within the domain enables us to make an important cancellation: $\"y+=+%28%28x-7%29%28x%2B7%29%29%2F%28x-7%29+=+x+%2B7\"$ , x not equal to 7. The graph of this function is a straight line WITH A HOLE at the point (7,14), and y-intercept at 7. (So there is NO vertical asymtote!) \n" ); document.write( "
