Here we will use the fact that a function is piecewise continious in an interval if it has only finite number of discontinuities in it .
a. f(x) = 1/x , x ∈ (0,1] is piecewise continious in (O,1] as it is continious in whole Interval (0,1] so have no discontinuity in (0,1] .
b. f(x) = x^2 , x∈[0,1] , is also a piecewise continious function as being polynomial it is continious in whole interval [0,1] .
c.f(x) = 0 if x = 0
x^2 if x∈(0,1]
is also picewise continious as only possible point of discontinuity in interval [0,1] is x=0 but here also f(x) is continious and right hand limit have value 0 equals to functional value so it's continious in [0,1] hence piecewise continious .
d. f(x) = 0 , x∈[0,0.5]
= 1 , x∈[0.5,1]
is also piecewise continious as it has only point of discontinuity at x=0.5 in Interval [0,1].
e. f(x) = x^2 , x∈[0,0.5)
= 1 ,x = 0.5
=x^2 ,x∈(0.5,1]
is also piecewise continious as being polynomial it is continious in [0,.5) and (0.5,1] and only point of discontinuity is at x = 0.5 in [0,1] .
