Question

What is te value of f(2)

Answer 1

Answer:

f(2) = 1

Step-by-step explanation:

f(x) where x = 2

we plug this into the function named f(x) and solve with the value plugged in

f(2) 1/2(2) = 1

Answer 2

Answer:

$\large\boxed{f(2)=1;\ f^{-1}(1)=2;\ f^{-1}(f(2))=2}$

Step-by-step explanation:

We have:

$f(x)=\dfrac{1}{2}x$ and $f^{-1}(x)=2x$

f(2) → put x = 2 to the equation of a function f(x):

$f(2)=\dfrac{1}{2}(2)=1$

f⁻¹(1) → put x = 1 to the equation of a function f⁻¹(x):

$f^{-1}(1)=2(1)=2$

f⁻¹(f(2)) → put f(2) = 2 to the equation of a function f⁻¹(x):

$f^{-1}(f(2))=f^{-1}(1)=2$
