How do you find the limit of #3x+2# as #x->-3#?

Answer 1

There is no problem with evaluating the expression at #x = -3#; doing so will give us the value of the limit.

#L = lim_(x to -3) 3x +2#
#L = 3(-3) +2#
#L = -7#

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
