if `f(x)=x/(x-1)` then `f(a) / f(a+1)=?`

f(x)=x/(x-1) then (f(a))/(f(a+1)) is equal to a. f(-a) b. f(1//a) c. f(a^2) d. f(-a/(a-1))

f(x)=(x)/(x-1) then (f(a))/(f(a+1)) is equal to a.f(-a) b.f(1/a) c.f(a^(2)) d.f (-(a)/(a-1))

" 4.If f(x)=(x+1)/(x-1) then f(x)+f((1)/(x)) is

If f(x)=(x)/(x-1) , then what is (f(a))/(f(a+1)) equal to?

If f(x)=(1-x)/(1+x)" then "f(x)+ f(1/x)=...... where (x)in R-{0,1}.

If f(x)=(x)/(x-1) , then prove that (f(a))/(f(a+1))=f(a^(2))

If f(x)=(x-1)/(x+1) , then f(f(a x)) in terms of f(x) is equal to (a)(f(x)-1)/(a(f(x)-1)) (b) (f(x)+1)/(a(f(x)-1)) (f(x)-1)/(a(f(x)+1)) (d) (f(x)+1)/(a(f(x)+1))
