Question

lim x-> -inf -2 + (3-x)^1/2 is it equal to positive infinity ? but how?

Answer 1

lim -2 + (3-x)^1/2
x->-inf


lim -2 + lim (3-x)^1/2
x->-inf x->-inf

-2 + lim (3-x)^1/2; 3--inf = inf
x->-inf

Answer 2

bravo

Answer 3

so does it mean that we just substitute x as - inf and then minus will cancel the minus ?
