Number of point of discontinity point in interval

If f(x)=[(8^(1/x),x = 0)], where [.] denotes the greatest integer function. Then f(x) (A) continous only at finite number of points (B) discontinous at finite number of points (C) discontinous at infinite number of points (D) discontinous at x=0

Number of points on a line is______

f(x)=min{x-[x] ,1+[x] -x} x lies in [0,3] , p is the number of points where it is discontinous q is the numbers of points where it is not differentiable . then find the value of p+q
