• The range of f is the domain of g and thedomain of f is the range of g.
•
f(a) = b if and only if g(b) = a.
•
(a, b) is on the graph of f if and only if (b, a) is onthe graph of g.
The function
f(x) = x3 + 7x + 5
is one-to-one. Since finding a formula for its inverse is beyondthe scope of this textbook, use Properties of Inverse FunctionsTheorem to help you compute
f ?1(5), f ?1(13), and f?1(?3).
| f ?1(5) | = | |
| f ?1(13) | = | |
| f ?1(?3) | = | |
