Answer:

The domain of the inverse of a relation is the same as the range of the original relation. In other words, the y-values of the relation are the x-values of the inverse.
Thus, domain of f(x): x∈R = range of f¯¹(x)
and range of f(x): x∈R =domain of f¯¹(x)
I redrew the triangle (just turned it around it make it easier to understand).
Im assuming your supposed to find like terms soo... as my final answer i got 11m-3n-13
