This is what I think


a) yes

b) and c)  The wording is strange but it is not contiuous at x=-1


d,e,f,and g are all -infinity


h) it is not continuous at x=-4


i,j,k,l all =0


m) Yes f is continuous at x=-2



n)    1

o)    -2

p) undefined

q)   f(-1)=-2

r)  f is not continuous at x=-1

s,t,u,v all =-2

w) f is continous at x = 3  (I think)

Infinite discontinuity at x=-4

x)  Jump discontinuity at x=-1


That is it I think.....
