Answer
Plot the points (1,0) (2,1) and (4,2) and connect them with a curve that approaches the y-axis in the direction of -$\infty$
Work Step by Step
To graph the inverse of a function, f, you must take the points of f and switch the x and y values. Then plot these new points and connect them so that it creates a reflection of f(x) with respect to the line y=x.
