Question

Verify that f(x) and f^-1(x) are inverse functions

f(x)=10x, f^-1(x)=x/10

Answer 1

f(x)=10x
y=10x
x=y/10
then change the plce of y and x after that you have your inverse function that is
y=x/10
f(x)-1=x/10

Answer 2

so both of them are inverse?

Answer 3

no the second function is the inverse of the first function

Answer 4

so only one of them? are you positive?

Answer 5

no each of the is the inverse of the other one

Answer 6

we have \[\left(f\circ f^{-1}\right)(x)=x\\
{(10x)\over10}=x\]
