APFIVE Parametrization of a Function and Its Inverse
The function f(x) = ln(x) is defined for x > 0. Which parametrization correctly represents both f(x) and its inverse function f⁻¹(x) = e^x?
A
f: (t, e^t) for all t; f⁻¹: (e^t, t) for all t
B
f: (t, ln(t)) for t > 0; f⁻¹: (ln(t), t) for t > 0
C
f: (t, ln(t)) for t > 0; f⁻¹: (e^t, t) for all t
D
f: (ln(t), t) for t > 0; f⁻¹: (t, e^t) for all t
