Inverse Relations. To find an inverse mathamaticaly there is one simple rule: Switch the x and y XY

You can do this with anything. Sets of Points: (, )(, )(, )(, ) Equation: = 3 - 9xy Now you have to solve for y :

You can also do this with a graph Graph the line: y = -2x + 3 Draw the line y = x Flip the line across this line. xf(x) x

In a mapping: Reverse the x and y values by switching the direction of the arrows? Is the inverse relation a function?

You can also do this with a table Graph the line: y = 2x -4 xf(x) xf(x)x xf(x)

You can also do this with a table Graph the line: y = x xf(x) xf(x)x xf(x)
