1) limf(x) en (-2)+ = (- 8 )/0+ = -inf =====> f discontinue en (-2)+
2) limf(x) en 2 = 0/0 forme ind.
une façon : poser V(x+2) = h -------> 2
f(x) = [h(h²-2)²-8] / h²(4-h²) = (h-2)(h^4 + 2h^3 +4) / h²(h+2)(2-h) = g(h)
= -(h^4 +2h^3 +4) / h²(h+2)
quand x-----> 2 , h-------> 2
limf(x) = limg(h) = -9/4 = alfa
