Limits question

OpenStudy (abbles):

I'm confused on #20...

OpenStudy (hafeda):

limit of a constant is the constant, and for other piece take left and right

OpenStudy (abbles):

I'm confused on which equations to use, because for 19 and 21 it is x>a or x<a, but for #20 there is x=a and x cannot equal a....

OpenStudy (hafeda):

think of it this way limit never takes the value itself, but get closed to it, which piece applies that info

OpenStudy (abbles):

Okay, I think I got it. Is the limit -2?
