Penjelasan dengan langkah-langkah:

$sf f(x)= dfrac{3}{2+ x^2} dan g(x) = dfrac{1}{sqrt{1-x} }$

$sf fog(x) = dfrac{3}{2+ left(begin{array}{ccc}{dfrac{1}{sqrt{1-x} } }} end{array}right)^2$

$sf fog(x) = dfrac{3}{2+ {frac{1}{{1-x} } }} end{array}right) = sf dfrac{3(1- x)}{2(1-x) + 1} = sf dfrac{3- 3x}{2-2 x + 1} = sf dfrac{3- 3x}{3-2 x}$
