| First I graphed y=x^2, then I found the inverse by switching the x's into y's. The next step is to square root both sides so the equation is now "plus or minus the square root of x equals y. Finally, draw a linear dotted line on y=x and folding across it. The final product should have the graph overlapping each other equally. Some graphs can pass both the horizontal and vertical line text like the graph on the left. |
