Answer 10

the point is, finding the inverse is change your subject of formula,before y = .... , make it into x = ... . then don't forget to replace subject X with Y again, and variable y inside the equation with X again. that is the inverse. ex: y= x - 1, change the subject to x, become: *x=y+1, then replace, the letter become: *y=x+1. the inverse not always be a function.

Answer 11

ok thank you but how you make y=x+1 from y=x-1
