## keeponbleeding Group Title Confirm that f and g are inverses by showing that f(g(x)) = x and g(f(x)) = x. one year ago one year ago

1. keeponbleeding Group Title

f(x) = 2/x and g(x) = 2/x

2. amorfide Group Title

f(g(x)) well if you had f(3) you would substitute 3 into where you find x so you have f(g(x)) so substitute g(x) where you find x in f(x) this means you are substituting the function g(x) into f(x)

3. ParthKohli Group Title

$\rm f(g(x)) = {2 \over \large {2 \over x}}$and$\rm g(f(x)) = {2 \over \large{2 \over x}}$Simplify.

@amorfide YA I AM BACK FROM THE DEAD

6. keeponbleeding Group Title

ummm x for both???

7. amorfide Group Title

showing that f(g(x)) = x and g(f(x)) = x. that is exactly what you should get well done
