Daily Graph 28-01-09

y=e^x-[x]-1

for [x]=1 y=e^{-2+ x}

for [x]=2 y=e^x-3

for [x]=-1 y=e^x

for every integer values the graph has a change in x by x+1 or x-1

for slope dy/dx>0 and d²y/dx²>0

this is the graph of y=e^{x}.

the blue lines r not a part o the graph.

i dont know how to do y=e^{x}-1

from this graph i gave can we get the required graph?
