1. )Let f(x)=3 ·x^9 -10 ·x^3 +2 and g(x)=c·x^n -7 ·x^3 +18 with c cannot = 0. Then

lim (-->infinite) f(x)/g(x)= infinite

c (>, < or =) to ________ and n (>, < or =) to ________ .

2.)The function

f(x)= -4·x^2+4 if x >(and equal to) -2

d-x if x -2

is continuous at x=-2 if and only if d = _______________

3.) The set of all points of discontinuity of the function

g(x)= x+4 / x^2-16

equals

a) {4}

b) {4,-4 }

c) {-4 }

sorry..hope you understand the notations...
