\[\lim_{x \rightarrow 2}f(x)+g(x)=f(2)+g(2)\] can u find f(2) and g(2) ?
anonymous
  • anonymous
is that what I do for the first one?

hartnn
  • hartnn
yup, find f(2) and g(2) then add.
anonymous
  • anonymous
is f(2)=1?
hartnn
  • hartnn
nopes, see the graph, when x=2, y=f(x)= 2 ok?
anonymous
  • anonymous
so, its the unshaded dot?
hartnn
  • hartnn
oh, wait, i think the dot is shaded to make the value of f(2) as 1. and not 2 so f(2)=1 as u correctly said before.
anonymous
  • anonymous
oh kay.. so first one is 3?
hartnn
  • hartnn
but g(2) is 0 isn't it? so, 1+0=1 is the value of limit, ok?
anonymous
  • anonymous
huh?
hartnn
  • hartnn
didn't u get g(2) = 0 ??
anonymous
  • anonymous
ohh yeah.. because theres no point
hartnn
  • hartnn
thats because when x=2,g(x) is on x-axis, so g(2)=0
anonymous
  • anonymous
for the second one is f(x)= 1?
anonymous
  • anonymous
and g(x)=1?
hartnn
  • hartnn
yup,both correct,so whats the value of limit?
anonymous
  • anonymous
2?
hartnn
  • hartnn
yup,thats correct,try 3rd.
anonymous
  • anonymous
and the next one is 0 overall right?
anonymous
  • anonymous
f(x)=0 and because its multiplying the total limit is 0
hartnn
  • hartnn
right,because f(0)=0
hartnn
  • hartnn
i think u are getting this,so just write what answers u get,i'll verify.
anonymous
  • anonymous
d is -1/0=0
hartnn
  • hartnn
anything/0 = infinity so d is -infinity
anonymous
  • anonymous
oh..
hartnn
  • hartnn
e is simpler,what did u get for e ?
anonymous
  • anonymous
e=8?
hartnn
  • hartnn
yup :)
anonymous
  • anonymous
f=2?
hartnn
  • hartnn
absolutely, good work :)
anonymous
  • anonymous
yay!!! thanks!
hartnn
  • hartnn
welcome :)
