The function f(x) = (x - 1)2 +3 is, in general, not one-to-one and thus does not have an inverse. However,
if the domain is restricted to [1, 0o), as shown below, then the function is one-to-one and therefore
invertible.
Determine f-¹. Graph f-1 along with the identity function, f(x)= = x. Using interval notation, list the
domain and range of both f and f-1.
