Inverse Functions Practice
1.) Find the inverse of the function y =
1
x !1
3
1
x ! 1 and its inverse .
3
Then graph the line y = x
to be sure that the graphs reflect
about this line.
Graph y =
Verify that the above functions are inverses.
f(g(x)) = x
AND
g(f(x)) = x
2.) Find the inverse of the function y = 3x – 3 .
Graph y = 3x – 3 and its inverse.
Then graph the line y = x
to be sure that the graphs reflect
about this line.
Verify that the above functions are inverses.
f(g(x)) = x
AND
g(f(x)) = x
