Please explain how to solve it.

Find lim (2x^2 + 5) x is approaching -2

my answer is 13. 2 x (-2)^2 + 5 = 13 My understanding is: when x ia approaching -2, y is approaching 13,

The correct answer isdoes not exist. Why?

Thank you

Are you sure you have the correct problem?. The limit definitely exists and you are right...it is 13 from both directions.
