Hello! I got a problem understanding this function g(x) = -2x²+4x, x < -1 13, x = -1 2x^3+3, -1 < x what is the lim g(x) ? x-> (-1)- I found it equals to 1, since 2(-1)^3+3 = 1. but apparently, it is incorrect. how come?

You are looking at the wrong side of $\displaystyle -1$. $\displaystyle \lim _{x \to - 1^ - } \text{ means }x < - 1$
