If `(2a+2b-x)=f(x)`, then `int_(2a)^(2b) x \ f(x) \ dx` is equal to

If f(a+b-x) =f(x) , then int_(a)^(b) x f(x) dx is equal to

If f(a+b-x)=f(x) , then int_(a)^(b) x f(x)dx is equal to -

If f(a+b - x) = f(x) , then int_(a)^(b) x f(x) dx is equal to

If f(a+b - x) = f(x) , then int_(a)^(b) x f(x) dx is equal to

If f(a+b-x)=f(x) , then int_a^b x f(x)dx is equal to (A) (a-b)/2int_a^b f(a+b-x)dx (B) (a+b)/2int_a^b f(b-x)dx (C) (a+b)/2int_a^b f(x)dx (D) (b-a)/2int_a^b f(x)dx

If f(2a-x)=-f(x) then int_(0)^(2a)f(x)dx is equal to-

If 2f(x) - 3 f(1//x) = x," then " int_(1)^(2) f(x) dx is equal to
