Consider the function $A(x)=\frac{x^2}{x^2+5},$ which of the following diecompositions show that $r(g(x))=h(x)?$ Answer res or no for each.

$($a$)f(x)=x_4,g(x)=\frac{x^2}{x^2+5}$

$($b$)f(x)=\frac{x}{x+5},g(x)=x^{2}q,$

$($c$)f(x)=\frac{x^2+5}{x},g(x)=\frac{1}{x^2}$

$($d$)f(x)=\frac{1}{x},g(x)=\frac{x^2+5}{x^2}$

$($e$)f(x)=x^2,g(x)=\frac{x}{x+\sqrt[\phantom{2}]{3}}$
