Given the following functions, use function composition to determine if $f(x)$ and $g(x)$ are inverse functions. $f(x) = x^2 + 3, x \ge 0$ and $g(x) = \sqrt{x - 3}$ (a) $(f \circ g)(x) = $ (b) $(g \circ f)(x) = $ (c) Thus $g(x)$ Select an answer an inverse function of $f(x)$

Step 1
$(f \circ g)(x) = f(g(x)) = f(\sqrt{x - 3}) = (\sqrt{x - 3})^2 + 3 = x - 3 + 3 = x$ Show more…

Verify that $f$ and $g$ are inverse functions by showing that a. $(f \circ g)(x)=x$ b. $(g \circ f)(x)=x$ $$f(x)=x^{2}-3, x \geq 0, \text { and } g(x)=\sqrt{x+3}, x \geq-3$$
