Continuity and DifferentiabilityHard
Question
Let [x] be the greatest integer function f(x) = 
is -
is -Options
A.not continuous at any point
B.continuous at 3/2
C.discontinuous at 2
D.differentiable at 4/3
Solution
f(x) = 
; 1 ≤ x < 2
=
; 2 ≤ x < 3
Hence f(x) is continuous at
, differentiable at 
& discontinuous at 2.
