Question

Find the limit of the function algebraically.
lim x approaches 0 (-7+x)/x^2

Answer 1

you know that 1/x -> ∞, so 1/x^2 -> ∞

as x->0, x-7 -> -7
So, (x-7)/x^2 -> -7/x^2 -> -∞

Answer 2

Thank you! the answer choices only say: Does not exist, 7, 0, and -7, so which would it be then?

Answer 3

Hmmm, do 0, 7, -7 exist?
