1f differentiable at 1 : so a+b=b+2b ... so a=2b
also LHD=RHD at 1... so 2a=b
from the above 2, a=b=0
g is continuous at 3, 3-c=9+b+1... so b+c+7=0
a+b+c=7
x^2+7xα+49(K+kα)=0
now what is "K"
where did u get this questin. i think u write it from the book directly so cannot think of typing mistake!
12) continuity of f at x=3
we know dat a=b=0 and c=-7
so f is not cont and dif at x=3
g is continuous at 3.. but not differentiable
62Ur question seems wrong dear..
where is k???
u have asked to prove te range of k!!!
24thats what i am searching for months..................i thought there may be some trick in it...................are u sure it is incomplete?????
Anyways help in other parts.........
62continuity is by equalting left and right hand limits..
differnetiability is by equatin left and right hand derivative..
This is stuff is not that difficult dear..
continuity of f at 1
a+b=b+2b ... so a=2b
differntiability of f at 1
2a=b
so a=b=0! (even i am getting this for part 2!
