Question

Use f(x) = 1/2x and f^-1(x) = 2x to solve the problems

Answer 1

Consider the given functions,

$\begin{gathered} f(x)=\frac{1}{2}x \\ f^{-1}(x)=2x \end{gathered}$

Solve for f(2) as,

$\begin{gathered} f(2)=\frac{1}{2}(2) \\ f(2)=1 \end{gathered}$

Thus, the value of f(2) is equal to 1 .

Solve for inverse of f(1) as,

$\begin{gathered} f(2)=\frac{1}{2}(2) \\ f(2)=1 \end{gathered}$

Thus, the value of f(2) is equal to 1 .
