Find the points of discontinuity and any holes.
please and thank you
we cancelled the (x+1)/(x+1) which is 0/0 for x=-1
so in our simplified expression when x=-1 y = -2
There is a "hole" at (-1,-2)
in the final expression the denominator cannot be zero, it is zero when x=-2
so the function is discontinuous at x=-2
so what are the points of discontinuity?
i thought that -1 and -2 were the pts of discontinuity
since you factor it?
