Can anyone find the inverse function of this:
(will you please show work!)
Thank you!
Hello, fruitkate21!
There are four basic steps . . .Find the inverse function of: .
[1] Replace with
[2] Interchange 's and 's: .
[3] Solve for
. . .
. . .
. .
. . .
. . . . . . . .
[4] Replace with
~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~
If you don't have to show your work,
. . there is a formula for this problem.
If . . . then: .
This is easily memorized:
. . (1) Switch the numbers on the main diagonal
. . . . .(upper-left and lower-right).
. . (2) Change the signs on the other diagonal
. . . . .(upper-right and lower-left).
