Use f(x) = 2 x and f-'(x) = 2x to solve the problems.
Marrrta [24]

Answer:

a) 1

b) 2

c) 2

Step-by-step explanation:

a) f(2) means find the output for \frac{1}{2}x when x=2.

\frac{1}{2}(2)

\frac{2}{2}

1

b) f^{-1}(1) means find the output for 2x when x=1

2(1)

2

c) If f and f^{-1} are truly inverses then f(f^{-1}(u))=u and f^{-1}(f(u))=u as long as u satisfies the domains.

So we should be able to conclude that f^{-1}(f(2))=2 with no work.

However, I will also show work.

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

f^{-1}(1)    since    f(2)=1 from part a.

2            since    f^{-1}(1)=2 from part b.
