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 Example In the graph below is shown in black is shown in red and is shown in blue Line graph with f x black line its inverse red line and y x blue line all intersecting at 4 4 Question Choose the graph of the inverse function Hint The line is drawn in blue in the answer choices Half a parabola with the points starting 6 0 intersecting 2 2 ending 6 3point5
