fucontinuous at x=1

i feel yes it is!book says not!

2)

f(-h) = -1
f(h) = 2h+1

where h is a "small" positive number (however small u want)

g(h)=f(h) + f(h) = 2h+1 + 2h+1 = 4h+2
g(-h) = f(h) + |f(-h)| = 2h+1 + |-1| = 2h+2

limiting value from both sides = 2

g(0) = f(0)+|f(0)|=1+1=2

u must have done some silly mistake!

LOL......i missed the definition of function n yeah very silly of me[3]
