Question

What is the inverse of ƒ?

ƒ(x) = 8x

Answer 1

y = 8x

Switch x and y to each other.

x = 8y

Now isolate y.

y = x/8

x/8 is the inverse of f.

Answer 2

@geerky42 so the answer is ƒ-1 (x) = 8x
?

Answer 3

x/8

Answer 4

One can find the inverse of function by switch x and y to each other then isolate y.

Answer 5

so is it A,B,C, OR D

Answer 6

How should I know?

Answer 7

A)
ƒ-1 (x) = 8x
B)
ƒ-1 (x) = x + 8

C)
ƒ-1 (x) = x - 8
D)
ƒ-1 (x) =
x
8

Answer 8

\[f^{-1}(x) = \dfrac{x}{8}\]It's D.
