Confirm that f and g are inverses by showing that f(g(x)) = x and g(f(x)) = x. (2 points) f of x equals eight divided by x and g of x equals eight divided by x

we can say that f and g are inverses of each other because f(g(x)) = x and g(f(x)) = x

Step-by-step explanation:

We need to confirm that f and g are inverses by showing that f(g(x)) = x and g(f(x)) = x.

We have

Now, finding f(g(x))

Put x = 8/x in f(x)

So, we get f(g(x))=x

Now, find g(f(x))

Put x = 8/x in g(x)

So, we get g(f(x)) = x

Therefore we can say that f and g are inverses of each other because f(g(x)) = x and g(f(x)) = x
