The Horizontal Line Test If it is possible to draw a horizontal line that touches the graph in at least two places then the function does not have an inverse Parabolic graph with no inverse Same graph with a red horizontal line that touches the graph in two places When the inverse function exists we can sketch a graph by switching the roles of x and y For every point on the graph swap the x and y values Another way of describing this transformation is to reflect the graph over the line
