If f(x) = `( x^2 + 1 ) / ( x^3 - 1 )` , then find `f (1/2 )`

If f(x-1)=x^(2) , then find f(x+1)

If f(x) = x^(2) - 2x - 3 then find f(A) when A = [(1,2),(2,1)]

If f(x)=(x^(2)-x+1)/(x^(2)+x+1) ,then find f(1+b)

f(x)+f(1-x)=2 then find f((1)/(2))=

Find domain(i) f(x) = (1)/(x - 5) (ii) f(x) = (3 - x)/(x - 3) (iii) f(x) = (x^(2) - 1)/(x - 1) (iv) f(x) = (| x - 3 |)/(x - 3) (v) f(x) = (1)/(2 - sin 3x)

If f'(x)=(1)/(x)+x^(2) and f(1)=(4)/(3) then find the value of f(x)
