Use the table to write a table of values for f-1(x). State the domain and range for f and for f-1.
A.
Domain of f = Range of f-1 = {1, 15, -10}
Range of f = Domain of f-1 = {2, -16}
B. No inverse function exists.
C.
Domain of f = Range of f-1 = {2, 15, -10}
Range of f = Domain of f-1 = {-15, 1, -16}
D.
Domain of f = Range of f-1 = {2, 15, 1}
Range of f = Domain of f-1 = {-15, -10, -16}
