Question

Will give BRAINLIEST!!!!!! Confirm that f and g are inverses by showing that f(g(x)) = x and g(f(x)) = x. f(x) = x2 - 3 and g(x) = square root of quantity three plus x

Answer 1

Answer:

Answer:

f(g(x)) = g(f(x))  = x and f and g are the inverses of each other.

Step-by-step explanation:

Here, the given functions are:

To Show:  f (g(x))  = g (f (x))

(1)  f (g(x))

Here, by the composite function:

⇒ f (g(x))  = x

(2) g (f(x))

Here, by the composite function:

⇒ g (f(x))  = x

Hence, f(g(x)) = g(f(x))  = x

⇒ f and g are the inverses of each other.
