Consider the function $y=\frac{1}{x}$y=1x which is defined for all real values of $x$x except $0$0.
Consider the function $y=\frac{2}{x}$y=2x
Ursula wants to sketch the graph of $y=\frac{7}{x}$y=7x, but knows that it will look similar to many other hyperbolas.
What can she do to the graph to show that it is the hyperbola $y=\frac{7}{x}$y=7x, rather than any other hyperbola of the form $y=\frac{k}{x}$y=kx?
