Key features of a reciprocal graph | Exit Quiz | Oak National Academy

Select the equations that can be plotted to give a reciprocal graph.

__________ is a line that a curve approaches but never touches.

• An asymptote

• An axis

• An intersection

• An intercept

• A reciprocal

Answer explanation

An asymptote is a line that a curve approaches but never touches. For a graph in the form $$y=k\over x$$ the $$x$$ and y$$ axes are asymptotes.

Match each of curve to the equation of its horizontal asymptote

Which of these equations could be the equation of this curve?
